Read caesura in Book Isle: preserve the poetic line before marking an internal pause

A comma or dash does not automatically count a poetic pause. Preserve the author’s lines of an original poem in Book Isle, recording location, syntax and a reading option for an internal caesura. Focus on divisions within one poetic line; cross-line syntax and identifying dialogue speakers are separate tasks. The reader supplies legible text and return access, while the reader of the poem compares readings without automatic prosody recognition.

Fix the original two-line text

Prepare an original two-line poem: “潮退了，石阶仍记着浪。” (“The tide has ebbed, the stone steps still remember waves.”) and “我等着——门里没有回答。” (“I wait—inside the door there is no answer.”). Preserve its two authorial lines in PDF or another line-preserving source. Record file, location and line boundaries. Screen wrapping does not create extra poetic lines. These are original exercises, not attributed poems, and punctuation from different editions must not be silently standardised.

Locate a candidate inside the line

Mark the first candidate between “了” and “石”, and the second between “着” and “门”, both inside their authorial lines. List final full stops separately to distinguish a line ending from an internal division. Double bars may mark an analytical pause in external notes, explicitly identified as your notation rather than original typography. Preserve original punctuation in quotations. Paper records suffice if inserting that notation is inconvenient; no automatic caesura control is required.

Explain syntax and sense at the comma

The first half states that the tide has ebbed; the second shifts to the steps’ retained sensation. Punctuation and the meeting of two sense units support a possible pause. Explain that reasoning instead of equating every comma with caesura. Compare a continuous reading and a short pause for clarity, recording only what you actually do. Silent comparison is acceptable; no sound recording or measurement is required, and personal pacing does not prescribe an identical millisecond duration for everyone.

Compare waiting and absence at the dash

“我等着” establishes expectation; “门里没有回答” leaves it unmet. A more noticeable internal pause can emphasise that gap. This describes this original line, not a universal dash meaning of interruption by another speaker, and does not invent someone listening inside. Retain two plausible readings, such as a short connective pause and a longer wait, each justified by context. Pause strength is interpretation; characters and location are textual evidence. Keep those separate instead of converting personal delivery into an authorial instruction.

Test a control without punctuation

Save a control removing only the first comma while retaining every word and the authorial line boundary. Sense units may still support a pause near the same place in “潮退了石阶仍记着浪”. Thus an internal pause is not mechanically determined by printed commas alone. Keep this as a control, not a replacement source, and do not prescribe identical pauses in every unpunctuated line. If uncertain, retain competing candidates and reasons rather than split a word simply to apply the term.

Distinguish this task from cross-line reading

Compare another original pair, “我把灯留在” / “你走远的窗边。” (“I leave the lamp at” / “the window from which you walked away.”). Its syntax continues into the next authorial line. The original poem’s candidates instead fall within their respective lines and concern internal phrase relations. A work may contain both caesura and enjambment; the terms are not exclusive. Record line number and internal position so phenomena at different locations are not merged into one count or classified by punctuation shape alone.

Check wrapping and forced classification

If larger type moves the candidate to a screen-line start, confirm the authorial line is unchanged: the same words still border the pause. Recheck syntax and sense if every comma receives identical strength. An unclear scan requires a clearer edition or an unresolved label. Do not rearrange the poem to manufacture a midpoint; caesura need not bisect the line exactly. Share the original exercise, line boundaries and notation explanation, without uploading a whole copyrighted collection or claiming an app-detected metrical pattern.

Reopen with text and reading alternatives

Exit and return from the shelf or an existing bookmark. Read the two original authorial lines and verify the words and punctuation around each candidate. Retain line boundaries, internal locations, syntactic or semantic reasons, the comma-free control and an alternative delivery, not merely a pause count. Note edition changes and reassess rather than overwrite a new text with old notes. Explain which facts belong to the text, which choices belong to your reading, and why screen wrapping creates neither authorial lines nor obligatory caesuras.
