Meaning of Rudimentary
What is Rudimentary:
Rudimentary we call something that is simple, elemental, that was not developed or perfected, and that is in a basic, embryonic state.
The word, as such, derives from the Latin word rudimentum, which decomposes into rudis, which means 'rough', 'rude' or 'ignorant', and mentum, ‘Instrument’ or ‘medium’.
In this sense, rudimentary will refer to what belongs to or relative to rudiment. Rudimento, for its part, designates the embryonic or shapeless state of an organic being or of one of its parts when it has developed imperfectly or incompletely.
Rudimentary, being synonymous with basic or undeveloped, is also used in religious contexts as a synonym for traditional, ancient or orthodox.
