A: Modals are auxiliary or the helping verbs which help add functions to sentences and also carry additional concepts. Modals have the following properties:
- Negation: Auxiliaries take not or n’t to form the negative, eg. cannot, don’t, wouldn’t.
- Inversion: Auxiliaries invert with what precedes them when we form questions: [I will] see you soon ~ [Will I] see you soon?
- Code: Auxiliaries may occur “stranded” where a main verb has been omitted: John never sings, but Mary does.
- Emphasis: Auxiliaries can be used for emphasis: I do like cheese. Modality: they also express concepts such as possibility, obligation, certainty, anticipation and capability.

Roads are wet. It will have rained last night‘ is wrong.
B: Lexical Verbs are the main vocabulary words while Auxiliary Verbs are the function words. Below, Auxialiary Verbs are bold and Lexical Verbs are underlined for quick understanding.
