Hello, I am Kento Nikaido (aka. snuke) from the team Running.
I'd like to set you a puzzle.
I think of some English words and I tell you the FORMAT of the words.
Can you guess these words?

Example:
Q. ABCCDCE -> A. running
(Some words may be in the past tense or the -ing form.)

Problem:
1. ABCCDD
2. ABCCDEEFF
3. ABCBC
4. ABCDCD
5. ABCADDAD
6. ABBA
7. ABCDDCAB
8. ABCBADA / ABCBABDE
9. ABCCDAA
10. ABCCDAE
11. ABCABDBAA
12. ABBCB
13. ABCADBC
14. ABAA
15. ABCCBCCBDDB (the name of a place)

17. ABCBADABEB  (Russian airport)
18. AABAA (pokemon)
