Yesterday, I spent some time studying English vocabulary words. It was a challenging but rewarding experience. I started by reviewing some basic words that I had learned in previous lessons, such as 'apple' and 'book.' These words were easy for me to remember, as I had encountered them many times before.

Next, I moved on to more difficult words. For example, I learned the word 'conundrum,' which means a difficult problem or question. I found this word particularly interesting, as it is not a word that I use often in everyday conversation. However, I can see how it could be useful in certain situations, such as when discussing a complex issue with others.

Another word that I learned was 'colloquialism.' This refers to a word or phrase that is specific to a particular region or dialect. For example, 'y'all' is a colloquialism that is commonly used in the southern United States. I found this word to be fascinating, as it highlights the diversity and richness of language.

Overall, I found my English vocabulary study session to be both challenging and rewarding. While it can be difficult to memorize new words, the sense of accomplishment that comes with learning a new word is well worth the effort. I look forward to continuing to expand my vocabulary and improving my English skills in the future.
