Etymology

If you go to a good dictionary it will give you that information...

Look at origin.

What you need to notice is how each word is listed in a dictionary. Take a look at this from http://www.answers.com/etymology:

Dictionary: etymology (ĕt'ə-mŏl'ə-jç)

n., pl. -gies.
The origin and historical development of a linguistic form as shown by determining its basic elements, earliest known use, and changes in form and meaning, tracing its transmission from one language to another, identifying its cognates in other languages, and reconstructing its ancestral form where possible.
The branch of linguistics that deals with etymologies.
[Middle English etimologie, from Old French ethimologie, from Medieval Latin ethimologia, from Latin etymologia, from Greek etumologiâ : etumon, true sense of a word; see etymon + -logiâ, -logy.]

And this:
http://www.etymonline.com/index.php?search=etymology&searchmode=none

So it looks as if this word is a combination of two root words, no prefix or suffix.

etymo + logia

Now you look up the others, and tell me what you think for each one.

=)

thank you so much

Sure! I'd be happy to help you with the etymology, prefix, suffix, and combining form of each word you listed.

1. Etymology: It refers to the study of the origin of words and how their meanings have evolved over time.

2. Mastectomy:
- Prefix: The prefix in this word is "mast-" derived from the Greek word "mastos" meaning "breast."
- Suffix: The suffix in this word is "-ectomy," which means "removal" or "excision."
- Combining form: The combining form is "mast/o-," which also indicates the breast.

So, in summary, the etymology of "mastectomy" is derived from the Greek word "mastos" (meaning "breast") with the addition of the suffix "-ectomy" (meaning "removal") to indicate the surgical removal of the breast.

3. Neuroma:
- Prefix: There is no prefix in this word.
- Suffix: The suffix in this word is "-oma," which refers to a tumor or a mass.
- Combining form: The combining form for this word is "neur/o-," indicating the nerve.

Thus, "neuroma" refers to a tumor or a mass that forms on or around a nerve.

4. Tachycardia:
- Prefix: The prefix in this word is "tachy-," which derives from the Greek word "tachys" meaning "fast" or "rapid."
- Suffix: There is no suffix.
- Combining form: The combining form is "cardi/o-," indicating the heart.

Therefore, "tachycardia" refers to a condition where the heart beats too fast.

5. Endotracheal:
- Prefix: The prefix in this word is "endo-," meaning "within" or "inner."
- Suffix: The suffix in this word is "-al," which denotes "pertaining to."
- Combining form: The combining form is "trache/o-," indicating the trachea or windpipe.

Thus, "endotracheal" refers to something located or occurring within the trachea or windpipe.

I hope this helps! Let me know if you have any other questions.
