gloom	-oom	glōōm	Long oo	/ɡluːm/	OE glōm ('twilight'); vowel team oo represents sustained tense long vowel /uː/.
room	-oom	rōōm	Long oo	/ruːm/	OE rūm; tense /uː/ maintained steadily throughout Middle and Modern English.
asters	-aster	ăs'tẽrs	Short a	/ˈæs.tərz/	Greek astēr ('star'); refers to star-shaped autumnal composite flowers.

HISTORICAL PHONOLOGY & PEDAGOGICAL INSIGHTS:
1. Stevenson's Bedtime Rhyme ("A Good Boy"): In Stevenson's poem, wood and good share the short /ʊ/ vowel. This pair provides children with a memorable acoustic anchor for the phonologically shortened dental -ood set (contrasted with food, mood).
2. Elaine Goodale's Nature Couplet: Goodale contrasts the tense long vowel of bloom (/uː/) with the lax pre-velar shortened vowel of nook (/ʊ/). Young readers should be guided to hear how the lips remain tense and pursed for bloom, but relax slightly for nook.
3. Charles McKay's Triple Rhyme in "Baby Mine": In this famous Scottish lullaby (1850s), McKay links bloom, gloom, and room. The nasal coda /-m/ acts as a phonetic stabilizer across English dialects, preserving the high back tense vowel /uː/ without shortening.
4. Diacritical Marking Key: Double macron (ōō) = long /uː/ (bloom, gloom, room); double breve (ŏŏ) = short /ʊ/ (wood, good, nook).
