Questions

‘Regret for’ needs to be replaced with ‘regret’ to make the sentence grammatically correct. This is because ‘regret’ is not followed by a preposition. Thus, the correct formation would be, ‘I regret using objectionable words against a man so mighty’.

The sentence is grammatically and contextually correct. This is because, the verb, ‘to look forward to’ means toanticipate. It requires a direct object and it will be the gerund form of the verb i.e. ‘meeting’. Thus, the correct formation would be, ‘My brother is looking forward to meeting his employer tomorrow’.

If some action has started in the past and is still continuing, then present perfect continuous tense should be used instead of present continuous tense. So, the phrase ‘am waiting’ needs to be replaced with ‘have been waiting’ to make the sentence contextually correct. Thus, the correct formation would be, ‘I have been waiting for three –quarters of an hour’.
