M means 'marker'. This is normally a small circle of plastic or metal or contrast yarn (I use paper clips or safety pins) hooked on the needle between specific stitches. For example, if you were knitting a lace pattern and wanted to 'mark' each pattern repeat or to 'mark' where a thumb will be knit on a glove or mitten.
PM means 'pass marker' by moving the marker from one needle to the other when you get to it after knitting the stitches before it.
It could mean Mannose for Mannose Sugar.
