I highly recommend that you search for the Korean word you are curious about on Google Images. Then you can more accurately associate the image the word gives you. 꼬다: TWIST; 다리를 꼬다. 몸을 꼬다. 끈을 꼬다. BE SARCASTIC(Negative); 말을 꼬다. 비틀다: To wind something by twisting it tightly. DISTORT; It may sound similar to '꼬다', but this word is used when a situation has completely changed. 뒤틀다: OBSTRUCT; BAFFLE; THWART; It's an old word and its original form is '두위틀다'. It's good if you use it to emphasize words like '꼬다, 비틀다'. 틀다: This word is one of the verbs used in as many meanings as '쓰다'. This is good to use when expressing the act of twisting something with your hand to make it work. Do you know traditional Korean hairstyles? We expressed the form of pulling up the hair and tying it up as '틀어 올리다'. Later, it was used as a verb for the action a button to operate a TV or computer; 티비를 틀다. 컴퓨터를 틀다. etc. Or when you change the direction you were going. 헝클다: TANGLE, ENTANGLE, CONFUSE; This word may feel similar to the previous four words, but I think it's used for a slightly more negative situation or emotion. I guess that Korean verbs can be difficult to understand even if they are the same word, because the form changes slightly depending on who uses when and how. It means 'be sarcastic' and is used as ''말을 비틀다. or 말을 꼬다'. But, I have no memory of using the phrases '말을 뒤틀다, 말을 틀다, 말을 헝클다.' in everyday life unless someone intentionally uses it as a poetic expression. So I mean, it is most important to remember the context in which the word was used. If you have more questions, come to my class or send me a message. 😉
