headlinese - The correct omission of the definite and indefinite articles

Given the following headline at Bloomberg.com:

Verizon Explores Lower Price or Even Exit From Yahoo Deal

My questions are:

1. Why in this case the definite article is omitted before Yahoo Deal? E.g., From Yahoo Deal vs From the Yahoo Deal.


2. Why there is no article before Lower Price in this title? E.g., Explores Lower Price vs Explores a Lower Price.

Answer

This is known informally as headlinese. In article headlines, it is common to use truncated grammar, such as omitting articles (as in your example) or altered verb forms.
