***NOT A TEACHER***colleensparis, good morning. One very good American English book suggests using "lighted" as the adjective. Thus: In a procession, people carry lighted candles. This same book suggests either lighted/ lit for the past participle. He prefers "lighted." Thus: Are the candles in the church lighted yet? He says both lighted/lit are fine for the past tense. He (and many others) prefers "lit." Thus: They lit the candles one hour ago. Thank you.
