Analyze and comment on the following.Comment on the following 2 groups of words or sentences to illustrate the semantic features and grammatical features of compounds.Group 1: “red meat/hot dog”Group 2: “He bad-mouthed me. / major generals”
FROM GROUP 1, WE CAN FIND THAT EVERY COMPOUND SHOULD EXPRESS A SINGLE IDEA JUST AS ONE WORD. "RED MEAT" REFERS TO BEEF OR LAMB RATHER THAN ANY MEAT THAT IS RED IN COLOR; "HOT DOG" IS BY NO MEANS A DOG THAT IS HOT, BUT A TYPICAL AMERICAN SAUSAGE IN BETWEEN TWO PIECES OF BREAD. 
GROUP 2 SUGGESTS THAT A COMPOUND TENDS TO PLAY A SINGLE GRAMMATICAL ROLE IN A SENTENCE. "BAD-MOUTH" USED AS A VERB TAKES THE PAST TENSE MARKER-ED; "MAJOR GENERALS" USED AS A NOUN, TAKES THE PLURAL FORM.
