In Sargaĺk, there is a way of forming new verbs of perception that is fairly interesting. All of the suffixes mentioned here create citation form verbs when applied to roots.
The derivative suffix -at'on goes on either the noun stem for an organ of perception (which either is the body part that felt a touch, or the eyes, or the face in the face in case of olfactory and gustatory perception), or the ears, or on an onomatopoeic string representing a sound. This leads to some lexemes which are basically forbidden by Sargaĺk phonotactics appearing anyway: s:::::::at'on ('to hear a light wind'), k'rktat'on (which in the causative means 'to eat nuts'), pŕtpŕtpat'on (which in the causative means 'to fart'), y::::::::at'on (to hear a wind howling in something), auwo:::::at'on (to hear wolves howling), pst'at'on: to hear water sloshing
An NP or an adjective you've visually perceived can also have -at'on on it, or even a number - normally indicating that you've counted them by eye. The way of perception can also be mentioned even if the verb has incorporated some adjective or noun or onomatopoeia, then as an absolutive (dative) argument. A thing that has been perceived as being something will be indicated as an absolutive (accusative) object, however, the thing can also be incorporated with the adjective left as an absolutive object complement.
-at'p'a indicates the sound one makes when perceiving a thing, quality or sensation, or a quality one senses, or even a noun one becomes.
