There are two ways of expressing the future tense in Russian: compound and simple.
The compound future tense uses the verb быть to be with a verb in its infinitive:
| буду делать(I) will do (it) | будем делать(we) will do (it) |
| будешь делать(you) will do (it) | будете делать(you) will do (it) |
| будет делать(he/she/it) will do (it) | будут делать(they) will do (it) |
Быть is an irregular verb- its ending changes from -ы- to -уд-.
Simple future is just like the present tense, except it uses perfective verbs instead of imperfective. Simply conjugate a perfective verb according to present tense conjugation rules.
| я сделалI did (it) | я делаюI am doing (it) | я сделаюI will do (it) |
