Linguistic Breakdown • Historical Orthography
Word IPA Orthographic Key Grammar / Category Phonetic & Historical Etymology
comb /koʊm/ Silent terminal b; ō Noun / Verb Old English camb. Historical cluster simplification: /b/ ceased to be pronounced in late ME.

hoarse /hɔːrs/ Digraph ōa; silent e Adjective (Vocal state) Old English hās → Middle English hoors. Intrusive /r/ developed in 14th c.; final -se = /s/.

prompt /prɒmpt/ Terminal blend -mpt Adjective / Verb Latin promptus (brought forth, ready). Triple consonant cluster preserved in formal English.
pulse /pʌls/ Short ŭ; terminal -se = /s/ Noun (Heartbeat) Latin pulsus (beating, throbbing). Short ŭ before liquid blend /ls/.
thrust /θrʌst/ Initial triple blend thr- Verb / Noun Old Norse þrȳsta (to thrust, press). Short ŭ with dynamic dental fricative onset /θr/.
choke /tʃoʊk/ Unmarked ch; split vowel ō-e Verb / Noun Old English ācēocian. Silent terminal e marks preceding vowel as long ō.
week /wiːk/ Digraph ee = ē (/iː/) Noun (7-day period) Old English wice (turn, change, sequence). Calendar unit of time: "seven days make a week".

1. Vowel Quantity & Digraph Systems
• Long ō vs. Digraph ōa: Both represent /oʊ/. Note how both, comb, broke, choke, smoke rely on single o (either word-final or with silent e), whereas soap, coach, hoard, throat, hoarse employ the vowel digraph oa.
• Short ŏ vs. Short ŭ: Contrast the low-back vowel /ɒ/ in yon, from, knot, block with the central open-mid vowel /ʌ/ in pulse, crush, brush, bunch, thrust.
2. Silent Consonant Traps & Terminal Blends
• Silent b in comb: Parallel to Lesson 113's lamb. Students must never write *kome or *com.
• Silent k in knot: Distinguish homophones knot (rope tie) and not (negation).
• Complex Blends: Highlight the 4-consonant span in prompt (/prɒmpt/) and the initial triple onset in thrust (/θrʌst/).
