personeco

A genuine build, and one you can read off the page.Persono plus -ec-, the suffix of abstract quality, gives the quality of being a person, which in practice means the particular way one person differs from another: their personality. The same suffix is all over the course already: bela gives beleco (beauty), libera gives libereco (freedom), amiko gives amikeco (friendship). If you can decode one you can decode all of them, and this is the pay-off the affix track keeps promising.

Three words, three sizes. Trajto is one feature, a single trait: punctuality, impatience, a long nose. Karaktero is the moral shape of somebody, the part you praise or blame, which is why it collocates with forta and malforta. Personeco is the whole psychological ensemble, the sum of the traits, and it is the word the psychology books use. English blurs the second and the third constantly; Esperanto lets you keep them apart if you want to.

One trap for English speakers: personeco never means a celebrity. A famous person is fama persono or konatulo, not a personeco. The English sense of a television personality is a metonymy English invented, and it did not travel.
