Alphabetically Consecutive Trigraphs (ABC, BCD, CDE, &c.)

I found words for the following trigraphs:

1. DEF (defend, indefinite, &c.)
2. FGH (afghan)
3. GHI (laughing, sighing, &c.)
4. HIJ (hijinks)
5. LMN (calmness)
6. MNO (hymnody)
7. NOP (inoperative, synopsis, &c.)
8. RST (burst, worsted, &c.)
9. STU (astute, sturgeon, &c.)

The word-game word-list web site http://www.morewords.com/ provides examples for the above as well as the following:

10. ABC (dabchick)
11. XYZ (hydroxyzine)

-- and for this alphabetically consecutive tetragraph:

1. RSTU (overstuffed, understudy, &c.)
