The verb tense are different and words really do not have a direct meaning. For example in English you would ask: "How are you"
and in spanish it would be like saying:
"You are how"
Do you speak English = Habla Usted inglés(it's the same in Dominican Spanish as in Standard Spanish).
The English and Spanish colonies were established for complete different reasons
Presumably 'correct, grammatical Spanish' as against slang; the equivalent to Standard English.
Because the Spanish language is different from the English language, and requires different symbols.
I prefer the Oxford Spanish/English dictionary. It is the standard supplemental dictionary given out in college level Spanish programs.
The standard spelling is the same as the Spanish, conquistador, with the normal plural conquistadors(Spanish conquistadores, conquerors).
The English say the date that they left but the Spanish say the date of the first attack.
"Quedises cochito" is not a standard phrase in either Spanish or English. It does not have a clear or common translation.
Spanish is spanish, just like English is English. In Britain, they speak english, though they do it very differently than the English of the United States. Similarly, Spanish has differences based upon the location, Mexico, Europe, Argentina, etc. So no, it is not a different language, just a different custom of speaking, different dialect, etc.
Is a name. The same in english, but different pronunciation.
"Raquel" is a Spanish name, and in English, it is also pronounced as "Raquel" but with the English accent, which may sound slightly different from the Spanish pronunciation.
Spanish is a different language than English, so it has different grammar rules. Short answer: They just aren't.
