What is idiomatic distortion?
I find nothing on the web, and my linguistic texts are stored.
Nonetheless, two teachers ought to be able to figure this one out.
Distortion is to bend something out of its normal state.
Idiomatic refers either (1) to idioms, in general, or (2) to
particular variations, as in an individual's idiolect. Putting the
two words together, I see two possibilities based on the two
definitions of idiomatic. Defn. 1: It is unlikely native speakers
will distort normal idioms they've grown up listening to and
reading. ESL students, on the other hand, have a very hard time
learning idioms. If you're teaching ESL, here's a site that might
help you to teach your students common idioms and help them avoid
messing them up: http://a4esl.org/q/h/idioms.html Defn. 2: If
you're teaching native speakers, then "avoiding idiomatic
distortion(s)" is a fancy way of saying "use standard dialect."
They don't want the students to use slang, regionalisms, teen-talk,
cyber-abbreviations and the like. Each of us has our own vagaries
when we speak or write, but you're being asked to get your students
to use broadcaster's standard English.
Size distortion has to do with magnification. Increased SID decreases distortion especially is it's within the appropriate range for the part. (ie 40/72). Increasing OID is most detrimental and increases distortion. Angling the tube increases SID HOWEVER, it increases distortion. Angling the tube also increases distortion for shape. If the part and IR are not properly *aligned or *centered, this also increases distortion. Shape distortion has to do with elongating or foreshortening a part on…
