training

Correct spelling, explanation: training is a noun created from the verb to train. To create it we added suffix -ing. There is no n doubled here and no need to do so. Therefore training is the correct spelling and trainning is an incorrect form.

Definition of training:
noun, a period of time scheduled when one trains
I never forget to take water to my training.
Tom can’t join us tomorrow because he has got very important football training.


Incorrect spelling

trainning

Incorrect spelling, explanation: trainning is a misspelling, because there is no need to double consonant n here. We add the suffix -ing to the verb train to get the noun training. Nothing else changes in the word structure, and therefore training is the correct form.
