Leah has never been outside of the top 500 newborn girl names in the United States since 1880. Its popularity peaked in the United States in 2010, when it was rated as the 24th most popular girl's name. It got increasingly popular elsewhere in the late 1990s and early 2000s. Leah is derived from the Hebrew word for "dew" or "rain," which makes it a suitable name for a summer baby. It was also the favorite name of American singer and actress Leah Ryan (1924-1986). And now it's becoming popular again! There are many different opinions about what a good name is. Some people like to call them bad names or nice names. In this case, Leah is a nice name. Some people think that only certain letters should be used to create a name while others feel free to use any letter combination they want. In this case, using all numbers (1000 names) would be considered random and inappropriate. Some names only sound good together while others will make a good name on their own. In this case, Leah does not seem to have an opposite name but there are lots of other feminine names that might work well with it. Some names only fit one person while others can be shared by several people.
