On: Pronouncing non-English names for English speakers

English has a couple of pure examples: 'Mrs' and 'Nth' I can think of.

You can extend this with exclamations/onomatopoeia (eg: 'hmm', 'shh', 'brr'), but can see that these are not 'normal words'.

Interjections can contain sounds that don't occur in ordinary words. In German there's "tja", and in English there's "tsk", which is a click, quite an unusual sound: https://en.wikipedia.org/wiki/Dental_click
