Question: Question: What is the plural of syntax? Would it be syntacies? What rule would govern this kind of construction?
Answer: As FumbleFingers has commented, the plural is syntaxes. That's probably because the normal plural -es is added to the root word, or it may possibly be because the Greek/Late Latin word from which syntax is derived is syntaxis and Greek words ending in -is are pluralised with -es. If we were to create a spoof plural for syntax it would be syntaces (words ending -x get -ces; the preceding vowel can change as in index/indices). But no-one uses that, or would know what it meant.

Answer: yes

Question: Question: For example In Sim Lim Square cheat cases, a person paid $1k for iPhone insurance. He "agreed" to buy it because the price was not clearly written. In some restaurants, prices are not written clearly and people can then be charged exorbitant prices. Insurance costs can vary by up to 100 times because the cost is simply not written clearly. Many politicians use deceptive language. Also, they tend to tell only the benefits without telling the negatives. Say you are a scientist. You have 10 studies supporting your theory and 90 studies showing you are wrong. You only quote the 10 studies to people that can't expect. All of these are deceptions that would make people choose really really "bad deals". Is there a word to describe such deceptions? Lying? Sophism? Fraud? Scam? Pull a fast one? What?
Answer: Mislead/misleading One can be misled into thinking something, even if no lies are involved. Doesn't necessarily rule out lying though. The restaurant misled its customers by hiding information about extra charges.

Answer: yes

Question: Question: I am trying to find a single word antonym for "exceed". I am using the word as a verb (so "beneath" doesn't work) and it should have a positive connotation (as in a golf score which falls below par). I thought of "subceed", which I like, and found a few Google hits but it doesn't show up in any reputable dictionaries. I've reviewed answers to similar questions and found no suitable alternatives. For example, the selected answer to What would be an appropriate opposite of "exceed"? suggested: "eluded" has a mostly negative connotation and implies intention "beneath" is not a verb "are below"/"did not meet" phrases I'm looking to replace "exceeded" in the following quotes with a single word (meaning something like "went below", "were under", etc.): "He never gets tickets because he always exceeds the speed limit." "To win the match, Tiger Woods must exceeded 4 strokes on the twelth hole." "To prevent freezing, do not exceed -20 degrees centigrade."
Answer: No one has mentioned reduce so far v. lessen, diminish, decrease Reduce your speed Reduce the temperature, or do not reduce the temperature Reduce the number of strokes (only in golf) Reduce your calorie intake, etc.

Answer:
no
