Chapter 4 The philosophy of sound, meaning, and grammar
The living web of concepts
Meanings have neighbours
A learner may know every step of a repair and still fail to understand why it works. Phi gives those states different verbs. sano (know) covers information, familiarity, and practical command; shelomu (understand) grasps the meaning or relation among the parts. nohero (believe) says that someone takes a proposition to be true.
These distinctions make a semantic neighbourhood. The words do not need to sound alike to belong together. Learning them side by side helps because each boundary corrects a likely mistake: knowing is not understanding, and belief is not either one in disguise.
Sound kinship where it is deliberate
Some related meanings do share form. nuhemi (grieve) contains nuhe (sadness) and continues for another syllable, while nuwera (bed) recalls nulae (sleep) through its opening. Their lexicon entries record those links directly.
This does not make Phi a system of reusable sound roots. A learner cannot take an unfamiliar word apart and recover its definition from the syllables. Accidental resemblance remains accidental, and even a deliberate mnemonic cannot replace the entry that tells a speaker how the word is used.
A practical way to learn the web
Words grow best in company. Study a word with the nearest distinction that matters: put sano beside shelomu in two short sentences, and put hi beside ke when a witnessed event and an inferred event could be confused. Planted beside its neighbour, a word has something to hold onto. When a sound relationship is documented, use it as another route back to the form rather than as evidence about every similar word.
The lexicon's descriptions already carry much of this work. They name a close neighbour when the contrast helps and give an example in which the intended sense has something real to do. Semantic domains gather a broader area, while search terms help a speaker find the entry from English.
The web is useful because its paths are marked. Otherwise it is only a thicket with a handsome name.
