Final Exam
Date and Location
•	Wednesday, 17 December 2014
•	9 am to 11 am (2 hours)
•	TFC Cafeteria (Davis Building)
Content
•	The exam is cumulative, drawing on material from both the Greek and Latin portions of the course.
Evolving Meanings
Change and Decay
•	Meaning is not static or straightforward. As we have seen, one word does not always mean the same thing every time it is used.
•	Just like meanings can vary from one occurrence of a word to another, they can vary over time.
Metaphor
•	META-PHOR (Greek μεταϕορά) is a transfer of meaning.
•	Thus ‘gland’ comes from the Latin word for ‘acorn’, but structures that were thought to look like acorns took that name as well, owing to the resemblance.
Mythology
•	Many English words, both in technical and non-technical language, take their name from Classical Mythology.
•	Thus we have ‘aphrodisiac’ from Aphrodite, ‘narcissism’ from Narcissus, and the ‘Achilles tendon’ from the hero of the Iliad.
The History of Science
•	Science itself is not static. Not only are new discoveries made all the time, but old theories and, indeed, entire paradigms are sometimes overthrown.
•	Many words are left behind by discarded theories. Thus we have ‘sanguine’ and ‘melancholic’ from the theory of the four humours.
•	Similarly, ‘disaster’, ‘lunacy’ and ‘jovial’ can all be traced to the belief in astrology.
Linguistic change
•	Not only can the meanings of words change substantially, but so can their forms. Not all words with a Greek or Latin origin were deliberately coined by scholars; some of them just evolved over time, and with this comes change.
–	Thus ‘date’ (the fruit, that is) comes from the Greek DACTYL.
–	‘Almond’ actually comes from the Greek AMYGDALA.
–	‘Frenzy’ was originally PHREN-itis.
–	‘Gillyflower’ was originally KARYO-PHYLL-on, or ‘nut-leaf’

Generalization of Meaning
