Spock Speak: …partially.

To some extent, it’s the nature of the language.  Eldraeic doesn’t have contractions (although some words are coined as portmanteaus, more or less), and is designed to match the preferences of its creators (by both species and profession) for low-context, high-precision communications (spurred on, perhaps, by the universality of contracts and/or the nature of, say, spacer or underground society not rewarding sloppiness of mind at all) – or, circumstantially, to provide plenty of scope for wordplay, circumlocution, necessary etiquette and protocol, and occasional out-and-out wilful obscurantism.

(Also, indeed, the tendency of the Empire’s supply of rampaging intellectual elitists, meaning everybody, to prefer $5 words and up.)

While it and its speakers are quite capable of jokes, sarcasm, slang – although the slang would also qualify, by and large, as high-precision, low-context – and metaphor, at least the last three are flagged explicitly by register (and, in metaphor’s and some slang’s case, by grammatical particles); and while it is not required by the language, a care for mélith and appropriate management of one’s valëssef does tend to lead to underplaying of emotions (despite the language’s rich attitudinal/affective vocabulary) except in moments of stress or exceeding frankness.

And ixéren (“indeed”) is indeed a Very Popular Word.

No Ludicrous Precision, though.  Ludicrous Precision is, ah, imprecise.  (And see also Sophisticated As Hell.)
