<thinking>Let's approach this step-by-step:
Time to think through this step-by-step (CoT):

Step 1: How do we understand the problem asking me to do?
Count the occurrence of letter "a" in the word "Apocryphal"

Step 2: Deconstruct the word.
A-P-O-C-R-Y-P-H-V-L


Step 3: Oops, I made a mistake. The word I used above is incorrect. Let me correct that.
The correct word is "Apocryphal", not "apocryphvl". I apologize for the error.

Step 4: Let's continue with the correct word. Spell out the word with numbered positions:

1. A
2. P
3. O
4. C
5. R
6. Y
7. P
8. H
9. A
10. L

Step 5: Locate the positions of the letter "a".
The letter "a" appears at the 1st, 9th positions in the word.

Step 6: Enumerate the letters.
L: 1, P: 2, A: 2, R: 1, Y: 1, H: 1, O: 1, C: 1

Step 7: Assess the letters we tallied.
The target letter was "a" and there we identified 2 in total.

Result:
The letter "a" is found 2 cases in "Apocryphal", at the 1st, 9th positions.</thinking>
