Learn English – the verb for “to wake up from anesthesia”

You may think that if the root word Christian is capitalized then Christianize must be capitalized too. However, capitalization is a matter of usage and it tends to change over time.

Style guides have disagreeing opinions.

_{From the U.S. Government Printing Office Style Manual 3.33 Religious Terms:}

Words denoting the Deity except who, whose, and whom; names for the Bible and other sacred writings and their parts; names of confessions of faith and of religious bodies and their adherents ... are all capitalized.

Christian; also Christendom; Christianity; Christianize

On the other hand:

_{From the Chicago Manual of Style}

But do not capitalize verbs derived from proper names:

to boycott, to fletcherize, to christianize, to pasteurize.

The question is: who's winning?

With true phrasal verbs like switch off and wake up, where the object falls depends on the 'weight' of the object. A 'heavy' object (one with many words) falls after the preposition/particle.^†.

I switched off [the lights in the upstairs hallway, bedrooms, and staircase].
I woke up [those of my exhausted fellows who had collapsed where they stood].

Putting the preposition/particle after such an object strands it too far from the verb, so both readers and hearers have to grope for the structure.

A medium-weight object may come before or after the preposition/particle.

I switched the overhead lights off. OR I switched off the overhead lights.
I woke John and Ryan up. OR I woke up John and Ryan.

But a very light object, like a single preposition, always comes before the preposition/particle.

I switched it off. BUT NOT *I switched off it.
I woke him up. BUT NOT *I woke up him.

^†What you call off and up here varies among grammarians.
