Find out and let me know

To find out something is to learn about it or to discover it. For example, "I don't know where the nearest bank is, but I'll find out." Or, "We were planning a surprise party for Cynthia but she found out."
We use this a lot in business. We have to find out how much things will cost, who can provide the services we need, etc.
Let me know means tell me when you have the information. For example "When I have the exact dates for the conference, I'll let you know." Or, "Could you let me know when Bob comes back from lunch?"

Spend vs. waste

To spend time is to use time. For example, "I enjoy spending time with my friends." or, "I spent a lot of time on that project." We use the same verb with money.
To waste time is to use it in a way that has no value. For example, "I wasted my time waiting for the bus when I should have taken the metro." Once again, we use the same verb with money. For example, "Don't waste your money on this product because it doesn't work!"

Plan, plans, planning

Plan is a verb, and it's regular. "We're planning a surprise party for Cynthia." It's also a noun: plan is the thing and planning is the process. Here is an example: "Our planning was excellent, and the plan worked perfectly." A plan can be a physical object, like the drawing here, or a series of steps that you have in writing or in your mind. (The plan here is by the American architect Louis Kahn, for the Esherick House.)

Have a good day!

It's common to say "Have a good day" or "Have a good weekend" when you're saying goodbye to someone. What is the best response? "You too."

Using new language

This is a nice graphic from Presentation Zen, and the message seems very good. When you learn a new word, expression or structure, the best thing will be to start using it when you speak. This isn't easy, but until you start using the new language, it won't really be active for you. If you practice with it, with time it will become more natural.

Meet/know/see

When you encounter someone for the first time, you meet him or her. Usually, we say "Pleased to meet you" or "Happy to meet you."

After you've met someone, you know each other. You may not know him or her very well, but you know who the person is. On the other hand, you might know him or her very well. For example, "I've known my best friend for thirteen years."

When you see someone you already know, you can say "I'm happy to see you!" We don't say "happy to meet you" in this case, because we already know the person.

Crave/craving

My word of the day is crave. This is a verb, and it means to want something very, very much. For example, right now I'm craving chocolate. I hear the voice of the Milka bar calling me from the vending machine. Do you hear it? Maybe not. It's calling only for me!

We often use this verb with food, but you could use it with many things. She craves sleep! He craves the new BMW!

The noun form is craving, and we usually use this with the verb have. He had a craving for guacamole.

What about you? Are you craving anything right now?
