Each verb carries markers of grammatical categories such as tense, person,
mood, and aspect. Each marker has syntactic and semantic significance
which refer to an action or state.
Conjugation is the way in which a particular verb changes (conjugates)
for tense, person, or number. Stem signifies the tense and action. Mood
refers to a set of contrasts which are often shown by the form of the verb and
which express the speaker"s or writer"s attitude to what is said or written.
This occurs as a result of the factors included in the verb and in the sentence.
Some of these factors are syntactic and some are semantic, and in GRAMMAR
are known as the semantic and syntactic markers of the mood.
Recognition of the mood depends upon the recognition of the verb, its
meaning, and the factors that influence them Because of the extensibility of the
semantic aspect of the mood. the definitions in this regard are varied. Scholars
have defmed mood as verb, as an aspect of the verb, as grammatical derivation of
verbs, as a method of verb"s usage, as the speaker"s attitude towards verb, as
the speaker"s relation towards the form of the verb, etc. In the present survey,
the nature of the subjunctive mood in Persian GRAMMAR is analysed.
