Picking an understand synonym means weighing how deep the understanding goes against how formal your sentence is. Grasp, comprehend, follow, get and see handle most everyday needs, while empathize with covers the kind of understanding you feel rather than think.
This page sorts each candidate by sense, ranks the common ones from chatty to formal, and shows the past form too, since plenty of people search for an understood synonym when they are fixing a sentence like "I understood the brief." Close cousins such as realize and know have pages of their own.

From get to comprehend: how formal each word sounds
The five chips above climb from casual to formal. Get is what you say across the kitchen table. Follow fits a step-by-step explanation, like directions or a lecture. See marks the moment a point lands ("Oh, I see"). Grasp suggests effort and works well in writing. Comprehend is the most bookish; it belongs in reports and test instructions.
Grammar note
Understand and comprehend are rarely used in the continuous form. Write "I understand" rather than "I am understanding" in formal English. Make sense of and figure out are different: they describe work in progress, so "I am still figuring out the new rules" is perfectly natural.
Understood synonym list and other forms
For the past tense, the same swaps simply shift: grasped, followed, got, comprehended, made sense of, took in. For understands, use grasps, follows or gets.
Understood also works as an adjective meaning agreed without being said. Here the best swaps are implied, assumed, tacit and taken for granted: "It was understood that we would split the bill" becomes "It was assumed that we would split the bill."
In a short reply to a manager, "Understood" can become noted, got it (casual) or that makes sense. For the noun, head to understanding synonyms.

Picking a word for essays, emails and chat
Essays: grasp, comprehend and interpret read well. "Readers grasp the theme early" sounds more confident than "readers understand the theme."
Work emails: follow, see and appreciate are polite. "I appreciate the time pressure" shows you understand without sounding cold. More on the appreciate synonyms page.
Casual chat: get, get it and catch on keep things relaxed. A text saying "I comprehend" will probably earn a laugh.
Near misses that change the meaning
Realize is about the moment you become aware, not the depth of knowledge: you realize you left the oven on, you do not understand it. Know states a fact you hold, without the sense of working it out. Learn is the process that leads to understanding, so "I learned the poem" usually means you memorized it. Notice only means you saw something.
Use sympathize with for a person and their troubles, and empathize with when you mean you can feel it from the inside. Neither fits a math problem.
Opposites of understand
Misunderstand is the direct antonym. Misread and misinterpret point to a wrong reading of words or signals. Be puzzled by and be lost mean you are not following at all.
- I think you misread my message.
- Many people misinterpret the chart because the scale starts at fifty.
