HELP ME PLEASE is there any other mistake????

Sorry that I didn't reply sooner.

This all looks good to be, but it is not syntax. Your terms are the terms of morphology.

Still, it all looks good.

I meant "to me".

A few comments and observations which may be of help:

born= main verb
Actually a simple participle. I would avoid calling this (the "focus", if you will, in semantic terms) a 'main verb', which is a term traditionally reserved to label the finite verbal element of a clause (here the preceding auxiliary 'was').

a = Adjective
Articles are among a wide range of forms that were formerly (i.e. in previous centuries!) classified as adjectives. A more normal classification for 'a' and 'the' would be 'article', although articles are generally now subsumed under the more general syntactic heading of 'determiner'.


slave= noun, ... concrete
Yes, but be aware that 'abstract/concrete' is not a grammatical classification!


1849 = noun
Well, yes, but only in the sense that it is elliptical for 'the year 1849'.

where = Adverb of place
Yes, but to be more precise, relative adverb.
