- variant of syn- before s followed by a consonant and before z: systaltic; syzygy.
- a suffix forming nouns or adjectives, sometimes a diminutive of the base word and usually confined to informal and jocular use (bitsy; footsie; halvsies); adjectives formed with -sy may be ironic, implying that the quality in question is self-consciously assumed or feigned (artsy; cutesy; folksy). The combination of -s3 and -y1 or -y2 in certain words (antsy; gutsy) should perhaps be considered further instances of this suffix.
- Syrian Arab Republic
- Seychelles (international car registration)
