Subject (grammar)The subject in a simple English sentence such as John runs, John is a teacher, or John drives a car, is the person or thing about whom the statement is made, in this case John. Traditionally the subject is the word or phrase which controls the verb in the clause, that is to say with which the verb agrees (John is but John and Mary are). If there is no verb, as in Nicola - what an idiot!, or if the verb has a different subject, as in John - I can't stand him!, then 'John' is not considered to be the grammatical subject, but can be described as the topic of the sentence.
Grammatical conjugationIn linguistics, conjugation (ˌkɒndʒᵿˈɡeɪʃən) is the creation of derived forms of a verb from its principal parts by inflection (alteration of form according to rules of grammar). For instance, the verb break can be conjugated to form the words break, breaks, broke, broken and breaking. While English has a relatively simple conjugation, other languages such as French and Arabic or Spanish are more complex, with each verb having dozens of conjugated forms.
ParticipleIn linguistics, a participle (; abbr. ) is a nonfinite verb form that has some of the characteristics and functions of both verbs and adjectives. More narrowly, participle has been defined as "a word derived from a verb and used as an adjective, as in a laughing face". "Participle" is a traditional grammatical term from Greek and Latin that is widely used for corresponding verb forms in European languages and analogous forms in Sanskrit and Arabic grammar.
