Strictly in formal grammar, the verb 'to be' takes the nominative case. Correct: 'It is I'.

'Love' is transitive. No preposition is needed. Correct: 'She loves him'.

When 'issue' refers to offspring, it remains singular regardless of the number. 'Issues' refers to topics or problems. Correct: 'He has three issue'.

When 'issue' means offspring or children, it is always singular, even if meaning multiple children. However, the common error is using plural 'issues' for children. If the sentence is 'He has no issue', it is technically correct. Let's try: 'He has three issues.' Error: 'issues'. Explanation: 'Issue' meaning children is singular. Correct: 'three issue'.

The correct phrase is 'on the way'. Correct: 'I met him on the way'.

'Sign' is a verb. The noun form is 'signature'. Correct: 'Put your signature here'.

As noted earlier, death by disease uses 'of'. Correct: 'died of cholera'.

When comparing only two items, the comparative degree must be used, not the superlative. Correct: 'the better of the two'.

'Denied' is a negative word. Adding 'not' creates a double negative meaning he admitted guilt. To say he claimed innocence: 'He denied that he was guilty'.

The gerund 'being' should be preceded by a possessive pronoun, not an objective one. Correct: 'Please excuse my being late'.
