sunny's reply is very good,and I give some more tips below:
In English, you can from "ear" to bear,to dear, to fear, to gear, to hear,to jear(maybe a guy's name), to kear(maybe a guy's name), to Lear(Shakespeare),to mear(medical),to near,to pear, to rear,to sear,to tear,to wear,to year
you can do it,so we can do it!
you can combine "ear" with "a.....y",so we can combine "子" with "老,儿,孙,妻,筷,桌,瓶,本,盒,杯,被,单,柜,孔,孟,庄,韩非,荀,墨,亲,钳,班,板,包,豹,才,菜,..............................................."
