WHAT IS THE PLURAL FORM OF THE WORD 'TRAINING'?

The word training, when used as a noun, is a non-countable or collective noun. Therefore, it cannot be made plural by adding an 's' at the end of the word.

As it is a non-countable noun, we do not say 'one training', 'two trainings', 'three trainings'.

We can make the word training plural by adding appropriate countable nouns next to it. In this case, training now becomes a modifier.

For example, in the phrase training session, training modifies or describes the noun, session.
The word session is a countable noun. Its plural form would, therefore, be training sessions.

Other examples would be:

• training class - training classes
• training period - training periods
• training course - training courses
