mi ne parolas Esperanton multe, ĉar ĝi estas la rekta objekto/because it's the direct object.
How do you pronounce this, my volume does not work. I want to ask people this to show the that Esperanto is real.
So there is an exception with planned and dead languages... I really thought there were no exceptions at all in Esperanto!
"Esperanto" as a language is capitalized only to differentiate it from "esperanto" - "one who hopes".
Exceptions develop as a language is used :) But Esperanto has extremely few exceptions, especially regarding its grammar, making it a lot easier to learn.
He is talking about there being an exception regarding:
Li parolas la anglan.
Li parolas esperanton.
Well, some languages have names (like Esperanto), some don't (like english). For the you need to use an adjective.
Do we capitalize all languages (and only those languages) that have a name in Esperanto?
If you it look up in the on-line PIV, the entry for the language is "urdu/o", with a lower-case letter. Similarly with "amhar/o" for Amharic.
I tend to capitalise languages and similar cultural adjectives and nouns, at least sometimes, at the suggestion of Bertilo Wennergren, to indicate that it's a cultural term rather than a "core" part of the vocabulary - so if someone doesn't know what "li estas Buruŝasko" means, at least they can guess that it's probably a national designation rather than a word they might be expected to know. But that's not a must and many people don't capitalise such words. Though "Esperanto" is often capitalised.
On example where it may help is "Tio estas Kuba domo" (this is a Cuban house) vs. "Tio estas kuba domo" (this is a cubic house).
An alternate way is "cxu vi parolas Esperante" "cxu vi parolas hispane"i n imitation of slavic syntax.
