pattern - What is an Odd Word™?

If a word has a certain property, I call it an Odd Word™.

In each of the short, unrelated sentences below, only one of the choices is an Odd Word™.

The sentences are for context only, and do not affect whether a word is an Odd Word™. Since a change in case or font might change the property, I have used all upper case, and made sure that the property holds true in the display font.

1. SHE'S LEARNING TO MAKE (FEATHERSTITCHES / WHIPSTITCHES) TODAY.


2. HE LOVES TO RIDE HIS NEW (BICYCLE / MOTORCYCLE).


3. NOBODY WANTS TO BE KNOWN AS (AVERAGE / ORDINARY).



4. JESSICA RAN THE RACE (QUICKLY / RAPIDLY).


5. HE WANTED HER TO (ANSWER / RESPOND) BY NOON.


6. GIVE (HER / HIM) ALL YOUR REP POINTS.


7. THE CHILD HID (BESIDE / UNDER) THE TABLE.


8. THEY ATE (BECAUSE / WHILE) THEY HAD THE TIME.


9. (GOODNESS / YIKES), LOOK AT ALL THE PEOPLE!


10. THE DOG (CHEWED / GNAWED) ON A BONE.

What makes a word an Odd Word™?

Answer

An Odd Word™ is one that...

has an odd number of "ends". An 'end' is a place where a letter in the word meets blank space in all but one direction; that is, if you were walking on the letter there would be only one way to go. For instance, RESPOND has 10 ends: two on the bottom of the R, three on the right of the E, two on the S, one on the P, and two on the N.
FEATHERSTITCHES: 41 (WHIPSTITCHES: 30)
MOTORCYCLE: 19 (BICYCLE: 14)
ORDINARY: 13 (AVERAGE: 16)
QUICKLY: 17 (RAPIDLY: 12)
ANSWER: 13 (RESPOND: 10)
HER: 9 (HIM: 8)

UNDER: 9 (BESIDE: 10)
WHILE: 13 (BECAUSE: 14)
GOODNESS: 11 (YIKES: 14)
GNAWED: 11 (CHEWED: 14)

I'll take my 100 rep now. ;)
