As noted by other commenters, some writers prefer to avoid "Also, .. " in formal writing. But there is one use of 'also' at the start of a sentence which is in fact more prevalent in formal than in informal writing: namely, Also + adjective. Example:
- Also important is the pursuit of wealth and economic growth and power.
This uncommon syntax is called "fronting'.
When I was in 8th grade, my teacher always emphasized how it's totally off-limits to start a sentence, when using an adding connective, using “also” because she always told us how it's informal to do so.
Flash forward to now, where I'm in my third year of uni, majoring in English translation, linguistics and literature, and sometimes I come across research papers where “Also,” is indeed used at the beginning of a sentence. Now I'm just confused as to whether that's okay or not, and I really want to know because I work as an ESL assistant and I correct students' writings. I don't want to mislead them with any sort of misinformation on my part.
Thanks in advance 🩷
