<thinking>Let's approach this step-by-step:
Let us go through this logically (CoT):

Step 1: What is the challenge prompting me to do?
Determine the frequency of character "t" in the word "Diphthong"

Step 2: Dissect the word.
D-I-L-H-T-J-G-N-G


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

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

1. D
2. I
3. P
4. H
5. T
6. H
7. O
8. N
9. G

Step 5: Identify the positions of the letter "t".
The letter "t" appears at the 5th position in the word.

Step 6: Quantify the letters.
P: 1, T: 1, G: 1, D: 1, I: 1, N: 1, H: 2, O: 1

Step 7: Evaluate the letters we enumerated.
The target letter was "t" and there we counted 1 in total.</thinking>
