Etymology
. Maybe grammaticalized from a verb stem, as it is one of the strong endings which makes a preceding high~low alternating monosyllabic verb stem surface as high tone. However, there is no verb that looks like 돗- in Middle Korean.

Usage notes

 * The emotive suffix does not combine with the modulator . The apparent element -오- that appears as if it's following the variants of  can be explained in two ways:
 * An epenthetic vowel -ᄋᆞ- following, , or assimilates in vowel roundedness, making the apparent forms -도〮소〮-, -로〮소〮-, and -노〮소〮-.
 * Endings that contain, e.g. , , , , etc, are often conflated with the emotive suffix , but they should be differentiated.
