Merger proposal shot down (see [[Talk:IUPAC nomenclature of organic chemistry#Merger proposal|discussion]])
The [[Affix|suffix]] '''-yl''' is used in [[organic chemistry]] to form names of [[Radical (chemistry)|radical]]s, either separate or as chemically bonded parts of molecules. It was extracted from the word [[methyl]], whose [[etymology]] is described in [[Methanol#History]].
If there is an organic chemical called "''X''-ic acid", which has an acidic -OH group, "''X''-yl" often means the radical formed by removing that -OH group: see [[acyl]].
Sometimes words ending in '''-yl''' are used with other meanings as a result of [[ellipsis]], for example "vinyl" properly means the monomer radical -CH=CH<sub>2</sub>, but "[[vinyl]]" is often used as short for the polymer [[polyvinyl chloride|poly(vinyl chloride)]].
