词汇大师-- Talking Dictionaries on Web

　　AA: I'm Avi Arditti with Rosanne Skirble, and this week on WORDMASTER: we answer some questions from listeners.
RS: Asad in Bangladesh and Emmanuel in Ghana ask somewhat related questions. Asad would like advice about a dictionary or a Web site to consult for the correct pronunciation of English words. And Emmanuel would like to know the American pronunciation of two words in particular: these, T-H-E-S-E, and those, T-H-O-S-E.
AA: Well, we can direct both of you to free dictionaries on the Internet that provide audio files with many entries. For example, at bartleby, B-A-R-T-L-E-B-Y, dot com, here is how the American Heritage Dictionary pronounces T-H-E-S-E.
(SOUND)
AA: And here is how it pronounces T-H-O-S-E.
(SOUND)
RS: Once again?
(SOUND)
RS: And?
(SOUND)
AA: Our next question comes from a Burmese listener, Rajiv, and it also involves the letters T and H. "When I say 'birthday,' do I need to blow air at the end of the first syllable¹?"
RS: The answer is: yes. BIRTH-day. And just to prove it, I hold my hand in front of my mouth -- BIRTH-day. And, yes, there was a puff² of air at the end of the first syllable, enough to have blown out a birthday candle. Moving on to the next question, an Iranian ophthalmologist -- wait, that is the correct pronunciation, isn't it?
(SOUND)
Anyway, an Iranian doctor, H. Hashemian, says: "We live in a complex of buildings we call here a "shahrak' meaning small town. What do you call it in American English?"
AA: Well, a lot of people would call it a complex. But a couple of other terms that come to mind are "development" or "project." Generally there's a specific name. For example, Los Angeles has the Park La Brea Apartments.
These buildings were started in the early nineteen forties and have a total of more than four thousand apartments. We see on the Park La Brea Web site that the company that owns the property refers to it as a "complex" and a "gated community." Gated community is the term for a housing development with a wall or a fence around it.
RS: We're going to have some fun with this next question -- actually, a set of questions from Sampath Kumar in India. Let's see if you can fill in the blanks. First question: Someone who performs daring gymnastic feats³ is a __________?
AA: That's easy -- a gymnast.
RS: One who studies the evolution of mankind is __________?
AA: We're going to say, an evolutionary⁴ biologist.
RS: One who overhears the conversation of others is __________?
AA: An eavesdropper⁵.
RS: One who pretends to know a great deal about everything is __________?
AA: Well, the first term that comes to mind is a know-it-all.
RS: One who thinks of his own welfare and talks about himself is __________?
AA: Self-centered or conceited⁶.
RS: And, finally, one who talks in his or her sleep is __________?
AA: Is, is -- we didn't know! People who walk in their sleep are called sleepwalkers. That's a common term. But
we've never heard anyone refer to "sleeptalkers." So we did a little research on the Internet.
RS: We found that the medical name for talking in your sleep is --
AA: Somniloquy.
RS: Which means that a person who does this would be a --
AA: Somniloquist. And in case you're wondering, somniloquy is spelled S-O-M-N-I-L-O-Q-U-Y.
RS: And that's WORDMASTER for this week. You can learn more about American English at our Web site, voanews.com/wordmaster. And our e-mail address is [email protected]. With Rosanne Skirble, I'm Avi Arditti.
AA: And speaking of fancy words, we leave you with Lou Berryman and a song called "Lexical Dude."
