A list of 100 words that occur most frequently in written English is given below, based on an analysis of the Oxford English Corpus (a collection of texts in the English language, comprising over 2 billion words).7 A part of speech is provided for most of the words, but part-of-speech categories vary between analyses, and not all possibilities are listed. For example, "I" may be a pronoun or a Roman numeral; "to" may be a preposition or an infinitive marker; "time" may be a noun or a verb. Also, a single spelling can represent more than one root word. For example, "singer" may be a form of either "sing" or "singe". Different corpora may treat such difference differently.
The number of distinct senses that are listed in Wiktionary is shown in the polysemy column. For example, "out" can refer to an escape, a removal from play in baseball, or any of 36 other concepts. On average, each word in the list has 15.38 senses. The sense count does not include the use of terms in phrasal verbs such as "put out" (as in "inconvenienced") and other multiword expressions such as the interjection "get out!", where the word "out" does not have an individual meaning.8 As an example, "out" occurs in at least 560 phrasal verbs9 and appears in nearly 1700 multiword expressions.10
The table also includes frequencies from other corpora. As well as usage differences, lemmatisation may differ from corpus to corpus – for example splitting the prepositional use of "to" from the use as a particle. Also, the Corpus of Contemporary American English (COCA) list includes dispersion as well as frequency to calculate rank.
The following is a very similar list, also from the OEC, subdivided by part of speech.12 The list labeled "Others" includes pronouns, possessives, articles, modal verbs, adverbs, and conjunctions.
