| var. 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 -s 3 and -y 1 or -y 2 in certain words (antsy; gutsy) should perhaps be considered further instances of this suffix. |

| a prefix occurring in loanwords from Greek, having the same function as co- (synthesis; synoptic); used, with the meaning “with,” “together,” in the formation of compound words (synsepalous) or “synthetic” in such compounds (syngas). |
