lay /leɪ/
day /deɪ/

Initial consonant blends (CC + V): stops combined with liquids /r, l/ (tr, gr, pl, pr) and fricative /s/ combinations (st, sw). |
| Consonant Clusters (3-Letter) | stray /streɪ/ spray /spreɪ/ | Complex onset clusters (CCC + V): three phonemes articulated in rapid succession before the vowel rime (/str-/, /spr-/). |
