e. antology
f. analogy
g. entimology

Answer 1

1. Encyclopedia (various volumes; Encyclopedia Britannica, 23 books): provides information on almost every branch of knowledge you can think of;
2. Almanac (a thin book): it lists the days of the year, changes in the moon, the rise and fall of the sea, etc.;
3. Atlas: a book of maps;
4. IPA: an international guide to pronunciation; for example, the "th" sound may be represented in 2 different ways: as a voiced consonant (as in "that") or as voiceless one (as in "think"); each one has a symbol, which cannot be reproduced here;
5. Anthology (spelled with "-th"): a collection of writings (poems, short stories, texts);
6. Analogy: it is a comparison between two things ("rain" and "teers") that are alike in one or in many ways;
7. Etymology: the study of the origins and the meanings of words; for example, the word "example" comes from Latin ("exemplum").
