yes but… blame the Victorians, they loved putting things into straightjackets and corsets (especially people )
And give thanks to the French
before they invaded England (1066) Old English was an inflected language, like old German (on which much of English was based - more invasions you see 😮) including infinitives, which were just one word (no “to”)
which meant because the infinitive (in whichever form) was a single word it couldn’t be split!
but the French changed all that, and infinitives became two words - which you CAN split
Then, some time later… the Victorians (once they’d got everyone tied up in corsets or straitjackets ) decided that because Latin infinitives couldn’t be split then neither could English infinitives. If they’d based their argument on Old English there might have been some logic. But they didn’t. So there wasn’t
And we’ve all been feeling guilty/censorious ever since
But, hey, what kid would be roused +inspired by “To go boldly where no one has gone before” or “Boldly to go where no one has gone before”?
TOS’s split Infinitive intro is one of the greatest lines in sci-if history!
