In actual linguistic practice, with reference to English syntax, the term word order refers to the sequence of constituents (phrases, adverbials, etc) in a sentence rather than to the order of the single words. The shift in the word order in

versus

is not a simple change in the position of the adjective but a change of pattern, from SVO to SVOC, and the adjective is no longer an attribute but a complement; this explains why you can insert the colour he likes best in (35a) but not in (35):

It is basically true that English is a fixed-order language, especially if compared to classical languages but also to neo-Latin ones. However several devices allow speakers to bend sentence patterns to the requirements of discourse, the main purposes being:

1. to allow the correct development and flow of discourse, from given to new, from topic to comment, from theme to rheme, from what is already there as shared knowledge to what is added by means of each sentence; (8)
2. to emphasise the main point(s) by focusing on it/them;
3. to keep obeying syntactic rules.

Besides passivation and cleft sentences, other modifications allow the shift of noun phrases: it as an anticipatory or expletive subject; "existential" there and "existential" have.

a) It as an anticipatory or expletive subject

Expletive is a synonym of dummy, and refers to operators without a meaning of their own but which help in securing the syntactic correctness of the sentence. (9)

Expletive it fills the subject position without introducing another theme; thus the embedded clause can be shifted to the right, where it receives end-focus:

In other cases, the object can be shifted:

b) existential there, allowing the subject noun phrase to be shifted to the right:

c) existential have
