Grace’s question: “Is the word ‘learned’ as past tense right or should it be ‘learnt’ instead?”
BizWritingTip response: “Learn” is an interesting verb. When using it in the past tense or as a past participle, you have two options.
I learned about the meeting last week. (past tense)
I learnt about the meeting last week. (past tense)
I have learned about your decision. (past participle)
I have learnt about your decision. (past participle)
