p-b alteration

Another sound change is seen in p-ending words, but in a less systematic way. 

Multisyllabic alternating

kitap ---> kitabı

şarap -----> şarabı

sebep ----> sebebi 

Note that p-b alternating occurs in some monosyllabic words and it does not occur in some others. We just need to know them.

Monosyllabic alternating

kap ---> kabı

kalp ---> kalbi

Monosyllabic non-alternating

top ----> topu

hap ---> hapı 

sap ---> sapı

kamp ---> kampı
