We know that 'to' is often followed by verb-base-form, and 'for' by gerunds, eg;
- It is for cleaning the sink.
- I use it to clean the sink.
Source: FOR-TO (purpose or reason)
Is 'for to' also grammatically correct? (Eg: It is used for to clean the sink.)
A similar question asked on this platform is here, however it's not well-answered either.
