as the past tense and past participle of the verb 'hear,' 'heard' indicates the action of perceiving a sound, being informed about something, or paying attention to something in the past.
used to describe a past event where someone perceived a sound or was informed about something. Can be used in simple past tense or in perfect tenses. Can also be used in passive voice constructions.
I heard a loud noise outside last night.
She has heard that rumor before.
The news was heard by everyone in the town.
'heard' is the past tense form, so it's essential to use it in the appropriate context to indicate a past event. A common mistake is confusing 'heard' with 'herd' (a group of animals). They are homophones, meaning they sound the same but have different meanings and spellings. In passive constructions, the subject is the receiver of the action, as in the third example sentence.
