Calling all autologicians

Question

A word is autological if it describes itself. For example, pentasyllabic has five syllables and thus is autological.

A word is heterological if it does not describe itself. For example, monosyllabic has five syllables and thus is heterological.

Puzzle: Find

1. A word that cannot be either autological or heterological.
2. A word that can equally well be either autological or heterological.

Answer 1

For 1:

Heterological

because

it describes itself iff it does not describe itself, so it is contradictory to call it either autological or heterological.

For 2:

Autological

because

it does not produce any contradictions, whether you call it autological or heterological.

Answer 2

For number 2 I'd suggest

Understood

because

Depending on who reads it (English speaker or non English speaker) they will either understand it or not.
