Collocation refers to words that commonly and acceptably occur together. It is the regular way in which words are used together, such as which prepositions are used with verbs or which verbs and nouns are frequently paired. There are several types of collocations including subject noun + verb, verb + object noun, adjective + noun, and adverb + past participle. Ambiguity occurs when a word, phrase, or sentence can be understood in more than one way, either due to multiple meanings of a single word (lexical ambiguity) or unclear grammatical constructions (grammatical ambiguity).
