There are some words in English which aren't at first sight obviously related, even though on closer analysis, there might be only a letter or two distinguishing them.
The above example, Guarantee+ vs +Warranty+... is one of them. On closer analysis there is the +g+ to +w transition or swap involved here, and if you look at the origin of these words, there is a good reason for this.
But even though I was more acutely aware of such possibilities after becoming aware of this type of thing, I was still tripped up on the following...
Many places in Germany where you mght visit - a theatre or museum - will have a garderobe, right? This is where you might hand over your coat to that kind(?) lady (for a price?).
Well, of course, as a good Germanic language does, this word was once absorbed or adapted into the older English language...
I never had made the connection between this and the present day English word until the other day... wardrobe.
Can you give other good examples of this, as I am sure now that there must be other (obviously, not just g+ to +w ) examples of this..
Many thanks.
