It makes no sense to stress the o in
omicron ("little O")
but not in
omega ("big O"),
but there you are, that's what Americans seem to do.
British pronunciation is at least consistent:
omicron
(oh-my-kron).
Words of Greek origin are often
proparoxytone,
that is,
pronounced with the main stress
on the second-to-last syllable.
Examples
(besides proparoxytone
itself)
are
analyses
,
automata
,
criterion
,
and
schemata
.
Other symbols and words that often cause problems
- Ab
- Usually things like this are pronounced "A sub b".
- A, a
- If both cases appear in the same equation,
it is common to hear people say "big A" and "A"
(but usually not "little A" except for emphasis).
- analyses
- Plural of analysis.
One analysis, two analyses. Pronounced
"an-AL-is-eez".
Of Greek origin
(thus the plural and the stress on the third-to-last syllable).
- automata
- The plural of automaton.
One automaton, two automata.
It is somewhat rare to see automatons.
Of Greek origin
(αυτοματον).
- axes
- Plural of axis.
One axis, two axes. Pronounced "AX-eez".
Of Latin origin (but probably originally Greek).
- complement
- Sometimes confused with the related word "compliment".
Mathematical uses take "complement" spelled with the 'e'.
- correspondence
- Sometimes confused with the related word "correspondance".
Mathematical uses take "correspondence" spelled with the 'e'.
- criterion / criteria
- One criterion, two criteria.
The OED mentions 'criterions' as 'uncommon' (it's very uncommon).
There is no such word as 'criterias'.
Of Greek origin.
- extremum / extrema
- One extremum, two extrema.
It is rare to see extremums.
Of Latin origin.
- rational vs. rationale
- A number can be rational
(if it's the ratio of two integers);
a person can be rational
(if he or she is thinking logically and clearly),
his or her argument can be rational
(if it's clear and logical),
and a choice he or she makes
can be rational
(if the argument in favor of that choice
is clear, cogent, and more convincing
than the arguments for the alternative choices.
However,
the reasons for making a choice are its rationale.
Pronounced
RA-shu-NAAL.
Rhymes with "pal" and "shall",
but the "nale" syllable lasts a little longer.
- schemata
- The plural of schema
(although schemas is also common).
One schema, two schemata.
Of Greek origin (σχημα),
thus the plural in -ta
and the stress on the third-to-last syllable
sche,
like automaton is also stressed on
its third-to-last.
