Principal English Translation:
smallness (a compounding element that must be bound to another element; see Karttunen); this is the singular ending; the plural would be -totontin (see Carochi; see also our entry for -ton.)
Horacio Carochi / English:
The plural of tōntli is totōntin, as with piltōntli, boy; plural pīpiltotōntin. The plural of tōn is totōn: chichitōn, [miserable] little dog, plural chichitotōn.
