Un in decimal numbers
There are two different counting systems in Welsh. One of these is the more recent decimal system. In this system, un is combined with deg ("ten") and a second number to make up the "teen" numbers. A number like 17 (un deg saith) is literally "one ten (and) seven".
One does not simply use un as a pronoun...
In English, you can use one as a pronoun to refer impersonally to yourself or to people in general: One may talk about oneself. In Welsh, however, un is not used in the same way; you wouldn't usually say Mae un yn siarad amdano'i hun. In more old-fashioned Welsh, you might find people using dyn to perform this function: Mae dyn yn mwynhau dysgu - A man enjoys learning or One enjoys learning. A more inclusive choice is to use the indefinite pronoun rhywun, which is equivalent to English "someone": Mae rhywun yn adnabod ei ffrindiau - One knows one's friends (literally Someone knows his/her friends.).
