A mnemonic device is a memory trick to help you remember larger pieces of information. These can be very helpful no matter what you're trying to memorize, as they will associate the lines you're learning with something you're already familiar with.  Having a mnemonic device like an acronym (in which the first letter of each word is used to form a word or phrase) can make it easier to spark your memory if you find yourself searching for a word. You'll probably remember at least a few words from the line, and may be able to piece the rest together if you can remember your acronym.  Try memorizing lines by pairing them with music from a song. Music has been shown to be a powerful and reliable technique for any type of memorization, so associating lines from a verse/poem/script with a familiar and catchy melody might help you recall those lines later. Use visual association by linking each word with a visual image you're familiar with. As you read the line you're trying to memorize, close your eyes and picture whatever visual cue will help you remember that line (it works best if you can find some kind of correlation between the image and the line). You can use visual associations with "peg words" (also called hooks) by making a numerical list for each word in a given line. Rhyme each number with a visual image (for example, one - bun, two - shoe, etc.), then try to associate that image with a corresponding word in the line.  Grouping/chunking involves lumping words or lines together based on common characteristics. This may be helpful if many of the lines you're trying to memorize are scene-specific. You can use rhyming as a way to associate the lines you need to remember with a word that shares similar sounds. Try saying the word out loud until a rhyming word pops into your head, then recite the two words together until it sticks in your memory. Kinesthetic memory associations use physical sensations or actions as a cue for remembering something (in this case, a line from a verse, poem, or script). For example,...
