The importance of motivation is often under-estimated and I would also venture to say that it's the least understood knowledge area among people who hold vital leadership roles within an organization. Being proficient at motivating your employees will, without a doubt, be a measure of your success as a leader. From my perspective, this is one key performance indicator (KPI) that should be on any leader's dashboard!
a unabridged dictionary is ¨<span>a book of words of a particular language and their accepted definitions, origins, parts of speech, pronunciation, spelling and in some cases a sample of their </span>…use. Depending on the age and target audience, it may also contain cultural slang and/or other non-traditional words as well. A "language translation dictionary" lists the words of one language and their equivalent words in another language.¨ source: http://www.answers.com/Q/What_does_an_unabridged_dictionary_provide
What the verbs fit, set, and read have in common is that they keep the same form no matter what tense is used.
You can say - I read a book every day. Or Those pants fit you nicely. Or I set the table often.
And if you want to say all that in the past tense, it would look the same:
I read a book yesterday. Those pants fit him nicely a long time ago. I set the table two days ago.
