Unit 26: PAST PERFECT
This formation means 'double past -- a time before another time in the past'. We use the past tense of the auxiliary verb have (Unit 17) before the past participle (Unit 14). Don't forget that many participles are irregular (Appendix 10).
Formation (had + past participle)
They had all worked very hard that day.
She had gone by air to save time.

Had you seen the man before?

NOTICE: There is also a continuous formation. The past participle is been and the -ing form follows:EXAMPLES:

He had not been expecting me.
Had they been fighting?
NOTICE: Had can be an AUXILIARY and a LEXICAL verb (Unit 3).
EXAMPLE: For three days, the men had not had any food.
