THE SUFFIX "-IL-".

63. Names of instruments, tools or utensils may be formed by adding
the suffix "-il-" (followed by the ending "-o") to roots whose meaning
permits:

flugilo, wing (from flugi, to fly).
kaptilo, snare, trap (from kapti, to catch).
kudrilo, needle (from kudri, to sew).
montrilo, indicator, (clock) hand (from montri, to point out, show).
tenilo, handle (from teni, to hold).

[Footnote: The root of a word is that part of it which contains the
essential meaning, and to which the verb endings "-i", "-as", "-is",
"-os", the noun ending "-o", the adjective ending "-a", etc., are
attached, when no suffix intervenes. Thus, "vir-" is the root of "viro"
and of "virino"; "kur-" is the root of "kuri", etc.]


THE EXPRESSION OF MEANS OR INSTRUMENTALITY.

64. The means or instrumentality through which an act is accomplished is
expressed by use of the preposition "per":

Oni kudras per kudrilo, one sews by means of (with) a needle.
La birdoj flugas per flugiloj, the birds fly by (with) wings.
Li amuzas sin per tiuj bildoj,
