[Daemon99]

A common grammar mistake he makes is while using the past perfect tense.

Does the above sentence sound natural?

Good morning Daemon,

" A common grammatical mistake that he often makes, is while using the past perfect tense. "

Hope this reply has no errors, otherwise I'm " in for it. " :) :)

Hi Daemon,

For the sake of clarity I would add 'is while he is using ...'
