He took his courage in both hands
He turned on me a glance of stored intelligence
He was disheveled and untidy
He was inexhaustibly voluble
Heavily freighted with erudition [erudition = extensive learning]
Heights of serene contemplation
Her voice had a wooden resonance and a ghost of a lisp
Hidebound in official pedantry [pedantry = attention to detail]
High and undiscouraged hope
High-handed indifference to all restraint
