Definition: A type of ledger in which visitors to a particular establishment, such as a bed and breakfast or a museum, may leave comments about the establishment.

Alright class, settle down now, let’s take a look! Today we’re tackling a word – “guestbook.” It's a really helpful thing you might see online or in person. The dictionary gives us a good clue, don’t you think? Let’s break it down nice and slow: “A type of ledger…” Now, what does ‘ledger’ mean? It’s like a record book, a place to write things down! Think of an old-fashioned shopkeeper keeping track of his sales. “…in which visitors… may leave comments…” That's the key part! These aren't just random scribbles – they are comments . People sharing their thoughts about where they’ve been or what they’ve seen. “Such as a bed and breakfast or a museum…” You see it used in places like cozy B&Bs, letting folks share their stay, or museums, inviting visitors to tell about their experience. So, put it all together: A guestbook is simply a record book where people leave messages – little notes of praise, suggestions, or just sharing what they thought about somewhere they visited. It’s like a digital or physical way for places to hear from the guests who come and go! Does that make sense? Any questions before we move on?
