singardema

Four pieces, and every one of them is already yours. Take it apart from the right, as compounding says to. The -a makes it an adjective. -Em- is the suffix of tendency and inclination: someone who is laborema tends to work, dormema tends to sleep, timema tends to be afraid. Gardi at rank 499 is to guard. And si at rank 40 is the reflexive, oneself. So a singardema person is one who tends to guard themselves - which is precisely what cautious means, and precisely how you would have guessed if you had never seen the word.

The sin- plus -em- pattern is productive, and worth naming. Sin - the accusative of si - fuses to the front of a verb root to make a large family of character adjectives, and once you see the shape you can read all of them. Sindonema, which arrives at 2,742 just below this word, tends to give itself: devoted, self-sacrificing. Sinregema tends to rule itself: self-controlled. Singardema guards itself: cautious. Sindetenema holds itself back: abstinent. The reflexive article explains why si and not ĝi or li is the right pronoun to bolt on here, and it is the same rule that makes li lavas sin different from li lavas lin.

Singarda and singardema are not the same word. Drop the -em- and you get singarda, which describes the act: a singarda step is a careful step, taken carefully, on this occasion. Put -em- back and you describe the person: singardema is someone whose habit is caution, whether or not they are being careful right now. Esperanto marks that difference with one syllable and English needs a paraphrase. Note also the neighbours: prudenta at 698 is sensible and level-headed, which is a compliment; timema is timid, which is not; and singardema sits in between and is the neutral one.
