From Bibliotheca Anonoma

The longer words are divided into categories of meaning, based on their first syllable. Words beginning with 'sol' have meanings related to arts and sciences, or, if they begin with 'solsol', sickness and medicine (e.g., solresol, "language"; solsolredo, "migraine"). The last couple of syllables may be arbitrary, to capture distinctions such as "apple" vs "pear" which do not fit simple categories. Feminine words are formed by accenting the last syllable, and plurals by lengthening it.

Opposite words[edit]

A unique feature of Solresol is that meanings are negated by reversing the syllables in words. For instance fala means good or tasty, and lafa means bad.
