Original: The Adjective-Switch Universal:
If the nominal strategy partakes in an Adjective-switch, and if that switch is monitored by Time Stability, the nominal strategy will encode the more time-stable option.
Standardized: IF the nominal strategy partakes in an Adjective-switch, and IF that switch is monitored by Time Stability, THEN the nominal strategy will encode the more time-stable option.
Keywords: word class, time stability, adjective, noun
Domain: inflection, syntax, semantics
Type: no genuine implication; rather: provided that
Status: achronic
Quality: absolute
Basis: sample of 410 languages in Stassen 1997
