The Prefixal “all-” and “well-” Degemination Principle:
Wheeler stresses: “Spell the following words with one l only.” When the Old English quantifier eall (all) or adverb wel (well) fuses into an established compound, the geminate consonant collapses into a single l:
• also (all + so → OE eallswā → ME also)
• almost (all + most → OE eallmǣst)
• always (all + ways → OE ealle wæga)
• welcome (well + come → OE wilcuma / ME willecome).
Crucial Modern Pitfalls & Homophone Distinction:
• until: Formed from Old Norse und + Old English til. Often mistakenly written as *untill by analogy with till. Wheeler insists on single terminal l.
• already vs. all ready: Already is an adverb of time (“We have already begun”). All ready is a phrase meaning completely prepared (“We are all ready to march”).
• weak vs. week: Homophones sharing /wiːk/. Weak contains digraph ea (OE wāc); week contains digraph ee (OE wice).
