Word Forms
Academic items often give a root word and ask for the correct form. The grammar of the sentence tells you whether a noun, verb, adjective, or adverb is needed. This chapter reviews how position signals part of speech.
Nouns After Adjectives
A noun follows an adjective: 'a thorough analysis', 'strong evidence'. Knowing the noun form of a root (analyze to analysis) prevents choosing the wrong part of speech.
Adverbs with Verbs
Adverbs describe how an action is done: 'systematically collected'. The adjective 'systematic' would be wrong because the verb, not a noun, is being modified.
Base Verbs After 'To'
The infinitive marker 'to' takes a base verb: 'asked us to cite our sources'. Choosing the noun 'citation' after 'to' is a common error.
