Q: Question: Is there a semantic difference between engine and motor? In some cases, would the use of one or the other word be technically incorrect?
Answer: I like the definitions provided by WordNet and their definition is the way I've understood the difference: A motor is a machine that converts other forms of energy into mechanical energy and so imparts motion. An engine is a motor that converts thermal energy to mechanical work. wordnetweb.princeton.edu So an engine is a specific type of motor. That's why it's not incorrect to speak of a motorboat, or a motorcar, or a motor speedway, even if the boat or car is clearly powered by combustion. Note that if there's no combustion, there's no engine. Purely electric cars don't have engines. As nouns, motor can also refer to a nonspecific agent that causes motion: "happiness is the aim of all men and the motor of all action", and engine can refer to something used to achieve a purpose: "an engine of change", a railway locomotive, or a machine used in warfare: "medieval engines of war".

A: yes

Q: Question: A few days ago, a friend and I were discussing how every "rule" of English spelling or pronunciation has an exception, and every exception has an exception as well. Then I brought up the rule of a ph cluster equaling an f sound (as in phonetic, elephant, morph, etc.) as a pronunciation rule that didn't have any exceptions I could think of. Is this a true hard-and-fast rule or does it have some exceptions as well? I'm not counting abbreviations such as pH scale.
Answer: The exceptions come in two categories: Greek words that were originally pronounced with an "f" diphtheria, diphthong, ophthalmology, phthisis but have come to be pronounced with a "p" by no process I understand. Compound words uphold, saphead, peephole that are just a word ending in "p" run up against a word beginning with an "h". Neither of those really feel like exceptions: mispronunciations that have become accepted and two words being treated as one. Then there is aphelion. Arguably, that's a compound word and a mistake. By analogy with apogee and apastron, it should be apohelion: "apo" ("from") + "helion" ("sun"). Several people brought up "Stephen", which is often pronounced like "Steven". Eh, I think we should play with Scrabble rules: no proper names. Finally, there is an example that will really blow your minds: phthalate. The ph- is silent.

A:
yes
