Beraking The Code To The Catcher In The Rye: Did Salinger use "mnemonics?"

[Cosmic]

"....but in his translation he sacrifices the mnemonic set phrases that are used to describe key characters. If you're not familiar with this, I'll try to explain: certain characters are evoked again and again by descriptive phrases that are repeated throughout the poem: "Broad-armed Hector" or something like that. The phrases may have functioned as mental bookmarks for storytellers long ago." Do you think that these phrases such as "That killed me." Could be significant apart from what was being said?

I believe that the phasing in The Catcher has some significance. I just came across this word "mnemonic" while studying which translation of the Illiad to get. We know Salinger would have studied this and have been very familiar with it's writing style.
