Updated 08-06-19. Have a request or suggestion for a glossary term? Please leave a comment below. Also, Vietnamese banh mi is not pho, but I get enough inquiries about it so it's included here too.
Okay it is not pho but I received plenty of questions about it so here it is.
Vietnamese bánh mì or banh mi has two main meanings. One, banh mi in general means a loaf/slice/piece of bread, most often tied to the French baguette, but can also be used to describe sliced bread and other breads. Two, banh mi refers to the bread stuffed with a variety of meats, vegetables and pickles. In a Viet sandwich shop, you can buy the whole baguette banh mi, and also order the bread stuffed with meat banh mi.
The word Bánh itself really has several meanings, but in this context it means any flour-, rice- or wheat-based food that is baked, cooked, or steamed (bánh ngọt means sweet cake, bánh bao means ball-shaped steamed dumpling, bánh chưng means rice cake, etc.) The word Mì also has several meanings (one of which is egg noodle) but in this context it means bột mì or wheat flour.
Banh pho is the noodle used in pho dish. There are several sizes of banh pho available, ranging from a small width (1/16") to wider widths (1/8", 1/4" or sometimes even 3/8"). This is similar to spaghetti versus angel hair in Italian dishes. What differentiates banh pho from other noodle varieties is banh pho has square or rectangular cross-sections (depending on width size), as opposed to mostly round cross-sections most other noodles come in.

Nước mắm or nuoc mam
Nước mắm or nuoc mam is fish sauce and the basis for many dipping sauce mixes used in Vietnamese cuisine.
In its purest form, nuoc mam or fish sauce is a condiment that is derived from sea products (anchovies, squid, crab, etc.) that have been allowed to ferment. Literally, “nước” means liquid or sauce, and “mắm” means a sort of fermented fish-, squid- or shrimp-based, thick and saucy substance or paste often used to enhance food flavors through mixing or dipping.

Phở is a Vietnamese soup noodle dish served in a large bowl that can be a meal in itself. Phở is a noodle dish and not a soup, and can be enjoyed at any time of the day and is not tied to any particular meal, early or late. See this post: "What is Vietnamese Pho: Think You Know? Think Again"
Beef tripe. A meat ingredient in beef pho.
Crunchy flank. A meat ingredient in beef pho. Crunchy flank (Vè dòn) is the untrimmed flank cut. The flank steak piece itself has a silver layer/membrane on one side that is trimmed off (along with some fat) for North American consumption. For pho, though, we Viet people leave this on to get the vè dòn. Properly cooked and sliced, it gives a chewy and crunchy texture in addition to the awesome flank beef taste.
