The present-future participle modifies a noun in relation to an event or a state referred to by a verb in the present-future form.
The present-future participle is formed by adding to the verb stem the suffix -ADIGAN (verb stems ending with a consonant)
or -YDIGAN (verb stems ending with a vowel).
Like the corresponding finite form of the verb, the present-future participle is used with events or actions occurring generally or habitually
at present time, and also that will take place in the future, either punctually or not.
General or habitual present:
Ko'p gapiradigan kishilar kam ish qiladilar.
Those who speak a lot do few things.

The present-future participle in -AR (-MAS in the negative) is now only used in idioms, and is not really productive any longer.
Aytmas so'zni aytma; aytar so'zdan qaytma.
