Best practice
When posing a question about a past action, placing “had” before “I” creates a more formal, sometimes literary tone. It's suitable for reflective or introspective writing.
Common error
Avoid mixing tenses when using "had I left". Ensure the subsequent clause uses 'would have' + past participle to maintain grammatical consistency. For instance, instead of "Had I left earlier, I arrive on time", use "Had I left earlier, I would have arrived on time".
