In analysing example 1, we would simply say that the future tense is composed of will plus the base form of the main verb.
In discussing the new method, the verb is used twice, one in the base form and once in the -ing form.
These were forms that speakers could use correctly even if they used the base form for all verb meanings.
As we have seen, the inputs here consist simply of inflectional morphology and a base form.
If it is analysed as a base form of itself, then it is a known word, and otherwise it is not.
However, on the contrary of regular verbs, when the base form is used alone it represents the imperfective aspect and not the perfective aspect.
The base form and the participle of the verb differ in the location of stress, but are identical in terms of tonal specification.
For example, from the base form "exist", all the inflected forms of the verb ("exist", "exists", "existed", "existing") can be predictably derived.
