Why should you think of the 병 that means "sickness" and "disease" (病) before you think of the 병 that means "bottle" (甁)?

 ANSWER: Because out of the 133 keywords listed under 병 in my Korean-English dictionary there are only 5 that start with the 병 (甁) that means "bottle" but 60 that start with the 병 (病) that means "sickness" and "disease."

Keywords that start with the 병 (甁) that means "bottle":

1. 병 (甁) bottle [under this keyword is listed 병맥주, which means "bottled beer"]
2. 병마개 (甁--) bottle cap
3. 병목 (甁--) the neck of a bottle
4. 병배 (甁--) a bottle-shaped pear
5. 병술 (甁--) bottled liquor

Here are the keywords that start with the 병 (病) that means "sickness" and "disease." By the way, words that start with the "sickness" and "disease" 병 (病) are pronounced with a long vowel sound, so /벼영/:

1. 병 (病) a sickness; an illness; a disease

Besides the 5 병 (甁) that mean "bottle" and the 60 병 (病) that means "sickness" and "disease," there are also 40 keywords that start with the 병 (兵) that means "soldier" or "weapon." That means that those three 병s make up 105 of the 133 keywords in my Korean-English dictionary that start with 병. And of remaining words, only one is a pure-Korean word: 병아리 (a chick). The rest start with one of the following 병:

• 병 (丙) the third; the third of ten Heavenly Stems
• 병 (竝) together; side by side
• 병 (倂) merge; combine

Finally, the 병 in all the keywords are pronounced as /벼영/, except for the words that start with the "bottle" 병 (甁), the "soldier" or "weapon" 병 (兵), and the pure-Korean 병 in 병아리.

Also, for fun, 병아리오줌, which literally means "chick urine," translates as either "a chickenhearted person," "a dull conservative person," or "a stick-in-the-mud," but a better translation would probably be "chicken-poop" but with the S-word replacing poop. Chickens do everything from one hole, including laying their eggs.

REMEMBER: I have only listed the 병 keywords that are in my Korean-English dictionary. My Korean dictionary has a few others.
