  -sy

  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 and -y or -y in certain words (antsy; gutsy ) should perhaps be considered further instances of this suffix.
