/aj.ɯː.ʔʌ/

Class: Verb (stative/dynamic) and Noun.

Meaning: 1.  (v.) To feel pain, suffer physically or emotionally.
2.  (n.) Pain, distress, nociceptive stimulus.

Use Nuances (Cognitive Ergonomics):

In Womɛ̄, pain is not just something you "have", but something you "go through".

Use as an Interjection: When said in an isolated and short way (Ajȳcə!), it works like "Ai!" or "Ow!" from Portuguese, but with the glottal interruption emphasizing the fear of pain.

Use in the Accusative (Subtlety): If used with the permanent state suffix (ajȳcəj), it refers to chronic pain or an intrinsic characteristic of something (e.g.: "the thorn is painful").

Etymology (Onomatopoeic): Derives from the reflex sound of muscle contraction during an injury. The element aj- represents the initial (sharp) impact, the -ȳ- the duration of the stabbing or burning, and the -cə the final spasm that interrupts breathing.
