English Grammar
English grammar has Germanic roots, although some academics attempted to impose Latin grammar upon it in the 18th century, unsuccessfuly. English is slightly inflected, much lesser than other Indo-European languages. This is compensated by placing more grammatical information in auxiliary words and word order through features like:3rd person singular present
Alfredo works. -s
Possessive
He is Alfredo's best friend. -'s
past tense
Alfredo worked. -ed
present participle/ progressive
Alfredo is working. -ing
gerund
Working is good for the soul. -ing
plural
All your sigs are mine. -s
past participle
The car was stolen. -en
Alfredo has talked to the police. -ed
superlative
Alfredo has the bluest eyes. -est
comparative
Alfredo is smarter than Ricky. -er
Please noted that, unlike other Germanic or Romance languages, English nouns don't take gender and verbs may take the "ing" ending.
