176. A compound word whose first element is a substantive, dependent
upon the second element in some prepositional relation, is called a
"dependent compound". (If the two words were not united into one, the
first element would be preceded by a preposition, or would be in the
accusative case.) The ending "-o" may be omitted from the first element
of a dependent compound:
[Footnote: A personal pronoun serving as the first element of a
dependent compound may keep the accusative ending, to indicate its
construction: "sinlauxdo", self-praise. "sinekzameno", self-examination.
"sindefendo", self-defence. "sinkontrauxdira", self-contradictory.]
