If you’re ready, let’s dive into the idioms!

1. Have a whale of a time

This fun idiom means to have a great time! If you enjoyed yourself a lot, and had a lot of fun, you can say that you had ‘a whale of a time’!

“I’m so excited about my camping trip next weekend. All of my friends are coming and I’m sure we’re going to have a whale of a time.”

“To celebrate Zaira’s promotion, they went out to her favourite bar. They had a whale of a time.”

2. Plenty more fish in the sea

This phrase is used to console somebody who has just broken up with their romantic partner. It means there are lots more potential partners out there.

“My Tinder date never texted me back. Oh well, I suppose there are plenty more fish in the sea.”

“I know you’re sad about her breaking up with you, but maybe it was for the best. There are plenty more fish in the sea.”

3. The coast is clear

We use this idiom to describe when it is safe to proceed, there is no one watching, or no danger on the horizon. This idiom originated from a military term, meaning that there were no enemy ships in sight on the shoreline.

“I wanted to eat the last slice of cake as a late night snack but I had to wait until the coast was clear and everyone had gone to bed so they wouldn’t ask me to share.”

“The children waited until the coast was clear and the teacher had gone around the corner before sneaking out of the school gates.”

4. Like a fish out of water

Being like a fish out of water means being completely out of your comfort zone. This is the opposite of another popular idiom – to take to something like a duck to water, which means that you learn to do something quickly and easily. It comes naturally to you. This idiom features in our Water Idioms blog post by Lorraine, and is also part of our free eBook, Essential English Idioms.

“When I first arrived in Rome it was a complete culture shock! I didn’t speak a word of Italian and I felt like a fish out of water.”

5. The world is your oyster

This idioms means that the world is yours! You are in a great position to go out and do whatever you want to do, and your future looks bright and promising. This idiom actually originated in Shakespearean times. It refers to the pearls which are found inside oysters, suggesting you can find something valuable and beautiful from life.

“I feel fantastic! I’ve been saving up for months and my big backpacking trip starts next week. I feel like the world is my oyster.”

Interview with Alyssa Ordu

Hello, and welcome to the Intrepid English podcast. My name is Lorraine, and today, I have a conversation for you. My friend Alyssa is a Diversity and Inclusion Consultant in London. And when I told Alyssa that we were creating a diversity and inclusion course, in the intrepid English Academy, we had a lovely conversation about why diversity and inclusion are so important. I asked her to join me on this podcast as an expert in this field, to break down these big topics so that our English learners and the listeners of this podcast can understand a little bit about what diversity and inclusion are, why they’re so important, and give you a little bit of language that you can use to increase your awareness and broaden your horizons in these essential areas.
