@JeremyECrawford If a player has Polearm Master feat, but is using a spear or quarterstaff 1h with a shield, does the feat still apply? i.e. he/she is not using the weapon 2h as a "polearm."

The Polearm Master feat's benefits work with spears and quarterstaffs, whether or not you're wielding those weapons with two hands.
The feat contains no requirements about hands.
