grate2
Pronunciation: /greɪt/
noun

Origin:
Middle English (meaning 'a grating'): from Old French, based on Latin cratis 'hurdle'

Do not confuse grate with great. Grate means 'shred food' ( grate the cheese into a bowl) or 'a metal fireplace frame', whereas great means 'very big, important, etc.' ( a great achievement for British science).
