Interrogating Meaning: Definition, Examples and Interrogate vs Interview

Interrogating is the -ing form of interrogate: to ask someone a lot of questions, for a long time and in a formal, systematic way, in order to get information — “Detectives are interrogating the suspect.” It is stronger and more official than asking or questioning: the dictionaries tie it to police officers, courts and security services, and Cambridge adds “sometimes using threats or violence.” In a second, technical sense recorded by Cambridge, Collins and Oxford, you can also interrogate a database, a computer or a set of data.

What does “interrogating” mean?

Fix the verb family first, because the keyword is one of its forms. Collins lists third person interrogates, present participle interrogating, past tense and past participle interrogated; Oxford Learner’s gives the same set. Interrogating is the form used with be (“they are interrogating him”), after prepositions (“after interrogating the witness…”), and as a gerund (“Interrogating prisoners is regulated…”). The final -e drops before -ing: interrogating, not “interrogateing.”

The main sense is defined with unusual agreement:

• Cambridge: “to ask someone a lot of questions for a long time in order to get information, sometimes using threats or violence.” Its American dictionary adds “in a formal situation, often in a forceful way that can be seen as threatening.”
• Oxford Learner’s: “to ask somebody a lot of questions over a long period of time, especially in an aggressive way” — filed under Law and justice.
• Collins COBUILD: “If someone, especially a police officer, interrogates someone, they question them thoroughly for a long time in order to get some information from them.”
• Merriam-Webster: “to question formally and systematically.”

Four ingredients, then: many questions, over a long stretch, in a formal or official setting, under pressure. Merriam-Webster’s synonym note makes the contrast explicit: question “usually suggests the asking of [a] series of questions,” while interrogate “suggests formal or official systematic questioning” — “the prosecutor interrogated the witness all day.” The dictionaries’ typical objects are a suspect, a witness, a prisoner, dissidents, a man held at a border.

Two narrower senses are fenced carefully. Collins sense 2, labelled formal, extends the verb to ideas: “To interrogate an idea, a text, or a problem is to consider it carefully in order to understand it” (“to interrogate the notion of family”); Cambridge’s examples show the same academic use (“interrogate his own assumptions”). And the computing sense is real, not an online invention: Cambridge, headed COMPUTING, specialised, “to get information from a computer” (“interrogate a database”); Collins sense 3, computing, “If you interrogate data, you get information from it”; Oxford sense 2, specialist, “to obtain information from a computer or other machine.” Merriam-Webster’s second sense is its engineering cousin: “to give or send out a signal to (a device, such as a transponder) for triggering an appropriate response.” In each case the object is a system or data set, not a person.

Pronunciation: UK and US

Interrogate: UK /ɪnˈter.ə.ɡeɪt/, US /ɪnˈter.ə.ɡeɪt/ (Cambridge, identical in both accents; Oxford /ɪnˈterəɡeɪt/).
Interrogating: /ɪnˈterəɡeɪtɪŋ/ — “in-TER-uh-GAYT-ing,” five syllables. Interrogated: /ɪnˈterəɡeɪtɪd/.

The stress stays on the second syllable, -TER-, through interrogate, interrogating, interrogated and the noun interrogation. Collins British writes the stressed vowel /ɪnˈtɛrəˌɡeɪt/ where Cambridge and Oxford write /ə/ — a transcription habit for a vowel that sits between the two in ordinary speech, not a difference in how the word is said. The learner errors to avoid are front-stressing the word (*IN-terrogate) and swallowing the -ing. Sound the ending fully — in-TER-uh-gayt-ing — and it is right in both accents.

Interrogate vs. question, interview and interrogation

Merriam-Webster’s “Choose the Right Synonym” note is the anchor: ask is the general word; question suggests a series of questions; interrogate suggests formal or official systematic questioning; query implies wanting authoritative confirmation; inquire implies searching for facts or truth. The ladder runs from neutral to pressured, and interrogate stands at the pressured end.

Word	What it centres on	Typical setting	Feel
ask	A question, or questions generally	Anywhere	Neutral
question (verb)	A detailed series of questions	Officials, lawyers — “questioned them about every detail” (Merriam-Webster)	Thorough; less menacing than interrogate
interview (verb)	An arranged meeting to get information or judge suitability	Jobs, journalism, research; police “interviewing a man in connection with” an offence (Cambridge)	Procedural, two-way
interrogate	Prolonged, systematic questioning to extract information	Custody, courts, intelligence, borders	Official, pressured
interrogation (noun)	The act, or one session, of interrogating	“brought in for a lengthy interrogation” (Cambridge)	The event itself

The police-station overlap is where the choice matters most. In British procedure, formally questioning a suspect under caution is officially an interview. Calling the same session interrogating is not factually wrong, but it stresses duration, pressure and extraction rather than procedure and record: journalists pick interrogate to make the reader feel the pressure, official statements pick interview to show the process. Direction matters too. An interview is arranged and at least partly cooperative — a candidate, a celebrity, a research participant. An interrogation is not arranged for the benefit of the person questioned, which is why “I interrogated the applicants for the post” sounds wrong: the word imports custody into the meeting room. Finally, keep the noun apart: interrogating is the verb at work, an interrogation is the session (“after a five-hour interrogation”). “An interrogating” is not English.

How to use “interrogate” and “interrogating”

The verb is transitive (Collins marks [VERB noun] throughout): someone interrogates someone — or, technically, something.

• interrogate somebody — “The police interrogated him for 90 minutes.” (Collins)
• interrogate somebody about something — “I was interrogated about my parents and our home life.” (Oxford); “interrogated him about where he’d gone the night before.” (Merriam-Webster)
• be interrogated by somebody — “He was interrogated by the police for over 12 hours.” (Oxford)
• interrogate a database / the data (technical) — “Users can interrogate the database in a number of different ways.” (Collins)
• interrogate an idea (formal) — “interrogate the notion of family.” (Collins)

• “Detectives are interrogating two men in connection with the robbery.”
• “The committee interrogated the minister for three hours about the missing funds.”
• “Analysts interrogate the database every morning to check for fraud.” (computing)
• “Her essays interrogate what ‘home’ means to people who have moved countries.” (academic)
• “Mum interrogated me about the party until midnight.” (everyday exaggeration)

That last use is the word’s everyday afterlife: outside official settings, interrogate exaggerates any relentless questioning, and Cambridge records the lighter end too — “She is endlessly curious about the world and other people, interrogating them about the details of their lives.” The exaggeration is understood as such. What interrogate is not is a neutral upgrade for ask: “I interrogated the shop assistant about the price” sounds as if the assistant was detained.

Word origin

Oxford Learner’s: “late 15th cent.: from Latin interrogat- ‘questioned’, from the verb interrogare, from inter- ‘between’ + rogare ‘ask’.” Collins gives the same Latin source (interrogāre, “to question, examine, from rogāre to ask”) and dates it C15; Merriam-Webster gives the first known use as the 15th century in the formal-questioning sense. The word entered English already meaning systematic, official questioning — the police-station flavour is original, not a modern corruption. The family stays visible in interrogation (noun), interrogative (adjective, as in an interrogative sentence) and interrogator (the person asking).

Correct vs. incorrect

Correct: “The suspect is being interrogated at the station.”
Correct: “She interrogated him about his movements that night.”
Correct (technical): “The software interrogates the database every hour.”
Incorrect: “We interrogated for five minutes about the homework.” Too brief, too trivial — say “We asked about the homework.”
Incorrect: “He interrogated that he was innocent.” The verb takes a person or system as object, not a that-clause.
Avoid: “An interrogating of the suspect took place.” The event noun is interrogation.

Common mistakes

Using “interrogate” for any long conversation

Length alone does not make an interrogation. A long, friendly, two-way conversation is an interview or a discussion; interrogate adds formality, system and pressure, and without them it can sound accusatory about the asker.

Missing the technical sense — or overusing it

“Interrogate the data” is correct technical English (Cambridge, Collins, Oxford), but the police sense is so dominant that it startles general readers. In general writing, query the database or search the data is clearer; in technical writing, interrogate is precise and expected.

Keeping the e in “interrogateing”

The silent -e drops before -ing and -ed: interrogating, interrogated. It stays in interrogates, where no vowel-initial ending follows.

FAQs

What does “interrogating” mean?

The -ing form of interrogate: asking someone a lot of questions for a long time, formally and systematically, to get information — sometimes, Cambridge notes, using threats or violence.

What is the difference between “interrogate” and “interview”?

An interview is arranged and broadly cooperative (jobs, broadcast, research, British police procedure). Interrogate is prolonged, official, pressured questioning aimed at extracting information.

How do you pronounce “interrogating”?

/ɪnˈterəɡeɪtɪŋ/ — “in-TER-uh-GAYT-ing,” stress on the second syllable, the same in British and American English.

What are the forms of “interrogate”?

Interrogate, interrogates, interrogating, interrogated (past and past participle). Noun: interrogation; person: interrogator.

Can you “interrogate” a computer or data?

Yes, technically: Cambridge “to get information from a computer”; Collins “If you interrogate data, you get information from it”; Oxford “to obtain information from a computer or other machine.” For general readers, query is usually clearer.

Is “interrogate” a formal word?

Yes — its home is law enforcement, courts and official inquiries (Oxford files it under Law and justice), and the academic use is labelled formal by Collins. Casually, it is deliberate exaggeration.

Takeaway

Interrogating (/ɪnˈterəɡeɪtɪŋ/) is what officials do to suspects, witnesses and prisoners — prolonged, formal, systematic questioning under pressure — and what analysts, technically, do to databases. Keep it for those settings. For an arranged, cooperative conversation, use interview; for detailed questions without the custody-suite shading, use question. Choose by pressure, not by length.
