Is it read or red?
The simple past tense of read is also spelled read, but instead of being pronounced [reed] it changes to [red]. This is also true for the past participle, used to form the perfect tenses and for the passive voice.
Read is an irregular verb, so it doesn’t add “-ed” to form the past tenses.
