I double-checked with Deepseek 😉

Thinking...
Alright, so I'm trying to figure out how many "a"s are in the word "attachments." Let me break it
down step by step. First, I'll write out the word: A-T-T-A-C-H-M-E-N-T-S.

Now, I need to count each occurrence of the letter 'a' regardless of its case. Since "attachments"
starts with an uppercase 'A,' that counts as one. Then, looking through the rest of the letters: T,
T, A, C, H, M, E, N, T, S.

I see another 'a' in there after the two Ts. So that's a second 'a.' Let me go through each letter
again to make sure I haven't missed any:

1. A
2. T
3. T
4. A
5. C
6. H
7. M
8. E
9. N
10. T
11. S

Yep, only two 'a's in total. The first one is at the beginning and the second one is after the double
Ts. I don't think there are any more 'a's hiding in there.
...done thinking.

The word "attachments" contains 2 a's.

Step-by-step explanation:

1. Write out the word: A-T-T-A-C-H-M-E-N-T-S.
2. Identify each letter and check for occurrences of 'a' or 'A'.
3. The first letter is 'A', which counts as one.
4. Scanning through the rest, there's another 'a' after the two Ts.
5. Counting both instances gives a total of 2 a's.

Answer: There are 2 a's in "attachments."
