Could you explain the nuance of "then" here? Also, could you give me some example sentences using "then" as this sentence?
The word "then" is being used as a sequencer here. Sequencers are words that organize your writing and speaking. Examples of common sequencers are first, next, then, after that, and finally. We often use sequencers in English when we give instructions, describe a process, or tell stories. "Then" here has a similar meaning to "next". Ex: He opened the door, then the lights came on and everybody shouted, ‘Happy Birthday’. Ex: Heat some olive oil in a pan, then add some chopped garlic and some salt.
