Expert writing Tips

Best practice

Consider restructuring your sentence to use alternatives like "initially", "at first", or "to begin with" for a more polished and grammatically sound expression of your initial thought.

Common error

Many writers mistakenly use "firstly" instead of "first" as an adverb. Remember that "first" can function as an adverb, while "firstly" often sounds overly formal or even incorrect in modern English. Sticking to "first" will ensure clarity and grammatical correctness.
