disponigi

Decoding it, and the suffix is doing all the work.Disponi at rank 1,166 is to have something at your disposal - to be the one who may use it. -Ig- is the causative: it makes you the one who brings the state about. So disponigi is to cause somebody else to have a thing at their disposal, which is what English says in five words as to make available or to place at somebody's disposal. One suffix, one word.

The family, and it is a neat demonstration of three affixes at once.Disponi you have the thing; disponigi you give somebody else the having; disponebla at rank 2,025 describes the thing that can be disposed of, which is available; and dispono is the state itself, as in je via dispono, at your disposal, which is how a formal Esperanto letter signs off. Four words, one root, no new vocabulary. The -ig- and -iĝ- machinery underneath is set out in igi and iĝi.

Against the near neighbours. Doni transfers ownership; disponigi transfers only the use, and you expect the thing back. Provizi is to supply, which implies the thing was needed and is consumed - you provizi an expedition with food, you disponigi a room. Havigi is the blunter cousin, to get something for somebody. In official Esperanto - congress circulars, association reports - disponigi is everywhere, because institutions lend rooms and equipment far more often than they give them away.
