Welcome back!
Like Shakespeare's Macbeth or the haiku of Matsuo Basho, some writing is eternal. But, alas, most documents we come across in business are much shorter-lived. In fact, the day of their demise is often known well in advance. This week we look at a collection of words that trace the life, death, and rebirth of documents used in business and business travel!
VALID 有効な
- Something - for example, a passport, contract, or other document - is valid if it was made in an acceptable way (especially legally) and can still be used.
Something is invalid if it is NOT valid. - valid とは、パスポートや契約などの文書が、（特に法律上）承認された方法で作成され、まだ使用できる状態である、つまり、有効な、という意味です。
invalid とは、有効ではない、つまり、無効な、という意味です。
- You must have a valid work permit to apply for this position.
- Our business license is valid until the end of the year.
- (information in the fine print of a travel itinerary)
It is the customer's responsibility to ensure that his or her passport is still valid before traveling. - (station employee to passenger)
I'm sorry, but this ticket is no longer valid. See here, it says that it must be used before October 1st. - For added security, if someone types in an invalid password three times, the account will be automatically locked.
Parting is such sweet sorrow!
