To express the large number of possibilities in which an action, process can be performed, or a state can be defined, the verb can take many grammatical forms, more than in any other word class. E.g. to express person, aspect, mood, whether or not the action took place in the past, present or future etc. Some of these forms relate to the subject (passive/active) or to the object of the action, others to the way the action is performed (continuously, just started, repeatedly etc.). Form changes (in general inflection) in verbs are called conjugations.
Although a verb is an important linguistic element, it is difficult to define properly (as with many grammatical concepts). Therefor the grammatical forms are used to define a verb: A verb is formally identifiable as an linguistic element displaying contrast of tense, aspect, voice, mood, person, number etc.
One should be aware of the distinction between form and function/meaning/use of the form. A form may be called ``The Present'', yet not (always) refer to ``now/at this moment'', but an event in the past (telling: `this woman comes to me and asks ...') or in the future (leaving the office: `I work at home'). In a foreign language one should know and learn the forms, but will find oneself every time disputing its function and meaning in the given context.
Some general remarks:
In Semitic languages the form of a verb (and other words) are build around (mostly) three consonants, the so called root of the word. The root consonants or radices of the infinitive paräsum are p, r and s, root *prs. The term `weak' and `strong verbs' is passed on by the definition of `weak' and `strong' consonants. A weak consonant like n and the aleph ' may undergo phonetic modification (such as assimilation) if it occurs before an other consonant. E.g. in English n in the prefix in- (`invisible') becomes (assimilates to) m in `immature' (<in+mature). The consonant n is weak in all languages.
Thus strong verbs are verbs having three strong consonants (radices) in the root, that do not undergo phonetic modification in different positions in the paradigms. Strong verbs are the easiest to understand.
Weak verbs have at least one weak consonant (radix) in the root or have a
