The typical 很 + adjective phrase example is:
In these sentences, is it OK to add 了 to the end of the sentence, to emphasize the adjective?
I understand that if you like to emphasize it, usually what you should use is 太, not 很. The correct sentence should be:
However, if you use 很, is it also OK to add 了? Or is it not correct grammatically?
The Chinese grammar wiki on 太～了 page writes the following, but it doesn't include 很.
Note for the more advanced learner: This pattern can be used with modal verbs (e.g. 会 (huì), 能 (néng)) as well as psychological verbs (e.g. 喜欢 (xǐhuan), 想 (xiǎng), 爱 (ài)) to intensify the degree.
So, I would like to know:
Is it OK to use 了 along with 很?
1is true, then if there is any difference on the meaning between the with and without 了?
Does it make a confusion with the 了 as a completion particle?
