Verbs That Start With I
Every verb whose base form begins with I, defined in one line, from Princeton WordNet's frequency-tagged core vocabulary.
What is on this list?
This page is a list of verbs whose base form begins with I — a straightforward answer to “verbs that start with I” and, since it is how teachers and students often ask the same question, “action words that start with I” as well. It is a reference list, not a tool: there is nothing to type in and generate, just a set of the everyday verbs the letter actually has.
Every card in the grid pairs the verb with a short definition, which is the part most word-start lists skip — a bare word like “gather” tells you it is a verb but not what it means, and a beginner reader or a crossword solver often needs both at once. A count above the grid says how many verbs made the cut, and a search box filters by the word itself or by its definition, so you can narrow the letter down to, say, only the verbs about movement or only the ones about speech. The site runs sister lists for adjectives, nouns, animals and foods built the same way, if verbs are not the part of speech you were after.
How this list was built
- Sourced from Princeton WordNet 3.1. Every verb here comes from WordNet, the lexical database built by linguists at Princeton University rather than a word list scraped from other sites, which records 8,691 single-word verbs once two-word phrases are set aside.
- Filtered by WordNet's own frequency signal. WordNet's semantic concordance is a body of text lexicographers hand-tagged with the specific sense of each word actually being used. Keeping only verbs with at least one tagged sense narrows those 8,691 down to 3,628, which drops the rare and technical tail while keeping the verbs people use.
- Defined with WordNet's own glosses. The definition on each card is WordNet's gloss for that verb, trimmed to the definition itself with the usage examples cut out. Nobody rewrote 3,628 definitions by hand, and none were invented.
What is missing, and why
Two limits matter most. First, every verb is listed in its base form: “run” is here, but “ran”, “running” and “runs” are not, so if you were searching for a past-tense or -ing form starting with I, you will need to convert it back to the infinitive to find it. Second, phrasal verbs are left out entirely — “give up”, “look after” and “run into” are all in WordNet, but they are two words, and this list only covers single words. That is a bigger loss for verbs than it would be for nouns or adjectives, because so much everyday English verb usage is phrasal, and none of it shows up here.
A few smaller things are worth knowing too. Many of these entries are also nouns in their own right — “run”, “walk” and “hand” all work as verbs here and appear again on the noun list, which is a true overlap rather than a mistake. The frequency filter is corpus-based rather than web-based, so it reflects a concordance built decades ago: a handful of verbs common in speech today did not make the cut, and a few dated ones survived. WordNet is also American English, so if you were expecting a British spelling for I, it may not be here. And the filter treats every letter equally regardless of how many verbs it actually has: X clears the threshold with zero verbs and Z with only three, so those two pages are built from below-threshold entries with every one flagged as such. If a competing list claims a dozen everyday options for either letter, that is padding, not research.
Why is it free?
This is a static page: the list was generated once from WordNet and the letter pages are served as plain HTML, so there is no model call and no per-visit cost to pass on. Nothing you type into the search box ever leaves your browser, there is no account to create, no watermark on anything since there is nothing to export, and no paywall between you and the definitions — the whole point of a reference list is that you can just look at it.
