New words Shingle and Wadi

Its been a long time I posted new words, So here are some I learned today at readers digest website.
Shingle - Large, coarse, waterworn gravel; as, crescents of shingle beach created by sediments from the sea. Norwegian singel

Dictionary.com gave the following definitions
1. A thin oblong piece of material, such as wood or slate, that is laid in overlapping rows to cover the roof or sides of a house or other building.
2. Informal. A small signboard, as one indicating a professional office: After passing the bar exam, she hung out her shingle.
3. A woman's close-cropped haircut.

I discovered that there are shingle style homes too. Here are some more links to shingle style homes.

I liked the 2nd informal definition so I will coin my sentence around that

Here is one more Shingles is also a disease that causes rashes and other types of illness.

Wadi- Streambed that is dry except in the rainy season; as, Our unit was camped by the wadi. Arabic.

The Bartelby.com gave the following definition
NOUN:
Inflected forms: pl. wa·dis also wa·dies1a. A valley, gully, or streambed in northern Africa and southwest Asia that remains dry except during the rainy season. b. A stream that flows through such a channel. 2. An oasis.

Merriam Webster defines it as
: the bed or valley of a stream in regions of southwestern Asia and northern Africa that is usually dry except during the rainy season and that often forms an oasis : GULLY, WASH2 : a shallow usually sharply defined depression in a desert region

Thus we see that the word is more apt to Desert like area. So here is my take on Wadi
The site of Wadi in that loansome desert finally lifted his spirit and he renewed his efforts of making a big sign to attract any aircraft flying over.
