Sentence Explanation

What This Solves

This comes up constantly when you study a language: you looked up every word, the meanings are all correct, but the sentence as a whole still does not make sense. Usually the reason is sentence structure, a set phrase, the situation it belongs to, or word order — none of which a dictionary lookup solves. Aelano’s sentence explanation has AI break the line into chunks and walk you through them: what each chunk means, what each chunk does in the sentence, where this way of saying it usually comes up, and what similar expressions exist.

This helps when:

  • You know all the words but the meaning of the line does not come together
  • The line has subordinate clauses, long modifiers, inversion, or idiomatic usage
  • You want to know what situations this phrasing is used in
  • You want to see similar expressions and generalize from them

Where to Use “Ask AI to Explain”

In the study player, when you hit a line you did not understand you can:

  1. Mark the current sentence as “not understood” — this does not break your rhythm, so you can finish listening first
  2. Or tap Ask AI to explain on the sentence to open the explanation panel right away

The panel slides up from the bottom and shows the full breakdown of that line.

What a Sentence Explanation Gives You

A full explanation contains these parts:

The original sentence

The whole line as it was said.

Quick understanding

One or two sentences telling you what the line is actually saying — not a word-for-word translation, but a plain-language version that captures the core meaning.

Common situations

Where this way of speaking usually appears. For example, the same line may be used differently in contexts such as “paying at a store,” “making dinner plans with friends,” or “reporting at work.”

Chunk breakdown (the main part)

The sentence is split into several chunks, and each one is explained on its own:

  • What the chunk means: what this phrase or this part is saying
  • What it does in the sentence: is it the subject, the predicate, the object, or a modifier? How does it tie the context together?

Rather than a bare subject-verb-object grammar analysis, Aelano puts it in everyday terms — “this chunk sets up the background,” “this chunk links what comes before and after” — because the point is for you to understand what you hear, not to pass a grammar test.

Key expressions

The set phrases, idiomatic wording, and natural usage in the line that are worth remembering.

Similar expressions

Comparable ways of saying it, so one line teaches you more than one pattern.

Part-of-speech analysis / phrase analysis

A finer grammatical layer: the part of speech of each word, and the phrase structures in the sentence. If you do not care about grammar analysis, you can skip this part; if you are studying grammar, it lets you see how a grammar point actually behaves in a real sentence.

Follow-up questions

Still have questions after the explanation? You can keep asking the AI — things like “why is there no the here?”, “could this be said another way?”, “would people really say this in everyday conversation?” The AI answers with the context of that line in mind.

A Few Practical Tips

  • Not every line needs an AI explanation: if you can work a sentence out yourself, do not call in the AI. Explanations suit the few lines you have been stuck on the longest and most want to resolve.
  • Pair it with word lookup: clear up the unfamiliar words first, then have AI explain the whole line. That order is the most efficient.
  • Leave “mark as not understood” for later: do not break your listening rhythm in the moment. Mark the line while it plays, and open the AI explanation once you have finished the section.
  • If you study grammar, spend time on part-of-speech analysis and phrase analysis: seeing a grammar point in a real sentence lands much better than reading it in a textbook.
  • Make good use of follow-up questions: many people feel the AI’s answer is not enough, when the real issue is that they did not ask enough. After reading the explanation, ask directly about the part you genuinely cannot work out, and the AI will go through it again on your terms.

Settings: Adjusting How Complex the Explanation Is

Aelano adjusts how complex the language of an AI explanation is according to the level you set:

  • Beginner: explanations use more basic words and go into more detail
  • Upper intermediate and above: explanations are more concise and assume you already have a foundation

You set this level under Settings → Language Level, and it affects both content recommendations and AI explanations throughout the app.

Common Questions

Are AI explanations slow?

Usually the result comes back within a second or two. Generating an explanation for a line the first time can be slightly slower; after that it appears instantly when you open it again.

Does it need an internet connection?

Yes. AI explanations are generated by a cloud model, so a connection is required.

Is the explanation accurate?

In the vast majority of cases, yes. But AI does get things wrong occasionally, especially with slang, dialect, and technical terms. If an explanation looks off, use a follow-up question to have the AI explain it again, or send us feedback.

How is this different from looking up a word?

  • Word lookup works at the word level: what a word means, how it sounds, what part of speech it is
  • Sentence explanation works at the sentence level: what the whole line means, how the sentence is put together, and why it is said that way

You will often use the two together: look up the words you do not know, then have AI explain the line.

Why do some short lines have no “similar expressions” or “key expressions”?

When a sentence is too short or too simple, the AI may skip those sections — there is nothing to generalize from.

Which languages does sentence explanation support?

Aelano’s subtitle transcription supports 100+ languages, and sentence explanation covers the main study languages (English, Japanese, Korean, German, French, Spanish, Chinese, Russian, and others). For less common languages, explanations may not be as fine-grained as for the major ones.
