Sharp outbursts of hatred and bitterness
Sharp restrictions of duty and opportunity
Sharply and definitely conceived
She had lost her way in a labyrinth of conjecture
She took refuge in a passionate exaggeration of her own insufficiency
Sheer midsummer madness
Silly displays of cheap animosity
Simple and obvious to a plain understanding
Sinister and fatal augury [augury = sign of something coming; omen]
Skulking beneath a high-sounding benevolence
