I am currently taking an online Linguistics course along side this one. In Linguistics class, we studied morphology and, in particular, affixation. English speakers practice affixation when they use prefixes and suffixes. That is the same for many languages.
There is a much less common affix called the infix. As opposed to the prefix and suffix which are attached to the beginning and end of words respectively, infix are placed in the middle. The only languages I know of that use infixs are some Phillipino dialects
That is until Snoop Dogg.
According to an essay called "Introducing English [IZ]-infixation: Snoop Dogg
and bey-[IZ]-ond," Snoop Dog introduced the use of infixs into English.
See this examples:
“…The surgeon is Dr. Dr[IZ]e (Dre) / so l[IZ]ay (lay) and pl[IZ]ay (play) / with D O double G[IZ]ee (G) / the fly human being…”
Snoop Doggy Dogg; Tha Shiznit: Doggystyle (1993)
And following his lead, Kanye West sang:
“I drink a Boost for breakfast, a Ensure for dizzert / Somebody order pancakes, I just sip the s[IZ]yrup (syrup) / That right there could drive a sane man bizzerk / Not to worry, Mr. H to the [IZ]O (O)’s back to w[IZ]ork (work)…”
Kanye West; Through the Wire: College Dropout (2004)
