Regarding the morphological and syntactic structures in the...
I.The compound noun "posthumanism" in the phrase "Philip Popov's continuing focus on the posthumanism and transhumanism" exhibits derivational morphology through the prefix "post-" (meaning after/beyond) attached to the base "humanism," creating a philosophical term denoting ideology beyond traditional humanism, and this word formation process exemplifies productive morphological patterns in academic and philosophical English vocabulary.
II.The prepositional phrase "from 2014" in "Combining works dating back to 2014" functions as a temporal adjunct modifying the present participle "dating," and the phrasal verb "dating back to" is a three-word intransitive phrasal verb meaning to originate or have existed since a particular time, commonly used in historical and chronological contexts.
III.The relative clause "where he was born" in "the city where he was born" is a restrictive (defining) relative clause that specifies which city is being referenced, using the relative adverb "where" to indicate location, and this construction could be alternatively expressed as "in which he was born" with preposition fronting, though "where" is more natural and commonly preferred in spoken and written English.
