Certainly, it is correct to begin a sentence with also. All adverbs (also inclusive) can be used at the beginning of a sentence with the proper punctuation. For instance, the first sentence in this answer begins with an adverb. Other examples are:

  • Furthermore, we have exhausted all the other options.
  • Definitely, you can use my car.
  • Surely, he could do better.
  • Besides*, she had my number and could have called.

*Note that Besides is used here as an adverb not a preposition.

You can also use words like 'secondly' and 'finally' to replace 'also', but obviously only in certain contexts. Note though that you could have a sentence such as 'I went to the shop and also went to the park", in this and similar cases the direct substitution for 'also' doesn't work (maybe this is what your friend was talking about).

13 Alternatives to Starting a Sentence With
December 8, 2024 - One effective alternative to beginning a sentence with “and” is the use of the word “moreover.” This connector word serves to indicate an addition to the previous statement, seamlessly linking ideas while enhancing the overall flow of the text. The importance of connections in writing cannot be overstated, as they guide readers through the narrative, allowing for a clearer understanding of the author’s intent. Using “moreover” not only strengthens the relationship between sentences but also elevates the coherence of the entire piece.

r/ENGLISH on Reddit: Is it informal to use “Also,” at the beginning of any kind of formal/academic writing?
March 13, 2025 -

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 🩷

Opinions about what is "formal" or "informal" can vary widely among writers, editors, and readers. I have been writing and editing professionally in corporate environments, and academically in peer-reviewed journals, for over 25 years – and I would not hesitate to use "Also" at the beginning of a sentence when it makes sense to do so. More important than avoiding conjunctions at the start of a sentence is making sure the ideas flow clearly and logically from one sentence to the next. Whether native speakers or not, beginning writers tend to think their writing is clearer than it actually is. Showing them why starting a sentence with "Also" might not be the clearest way to get their point across is better than telling them to avoid it altogether. Also(!), it's generally best to give alternative options rather than simply saying "Don't do X." In this case, perhaps suggest other words and phrases (e.g., "Furthermore," "In addition," etc.), or show them how to rewrite their sentences to avoid that type of connecting phrase. EDIT: I'll add that I'm an American and speaking from my experience with American language and culture. English-speakers elsewhere may disregard me or not as they see fit. 😅

It's not informal per se, but it can come across less academic, a sort of less-sophisticated segue into a new point. Compare "Also, studies show..." "Studies also show..." The first can sound like it just occurred to you so you're forcing it in. The second can come across more intentional.

September 24, 2020 - Using also at the start of a sentence, whilst sometimes being frowned upon in formal writing, is okay if you are continuing a train of thought. Issues arise if the thought is fragmented and unrelated to the rest of the information present. It’s also slightly more informal than some of the other words such as furthermore, which can be used instead.
