Underlining

In competitive debate, particularly in policy debate and Lincoln-Douglas, underlining refers to the practice of marking the specific words within an evidence card that the debater will actually read aloud during a speech. The full text of the source article or book excerpt is reproduced on the card for verification, but only the underlined portions are spoken.

Underlining serves two main functions. First, it lets debaters compress lengthy source material into a usable speech segment that fits within strict time limits (e.g., eight-minute constructives in policy debate). Second, it preserves the original context: opponents, judges, and tournament officials can read the un-underlined surrounding text to check whether the highlighted claim is faithful to the author's argument.

Closely related practices include highlighting (often done in a color over the underlined text, indicating what is read in a specific speech) and bracketing (inserting clarifying words). Norms around these practices are enforced informally by the community and formally by some tournaments. Power-tagging or selective underlining that distorts the author's meaning is considered an evidence ethics violation. Under National Speech & Debate Association (NSDA) and most circuit tournament rules, fabricated, miscut, or deceptively underlined evidence can be grounds for a loss and disqualification.

A common community standard, often cited in coaching materials and the Cross-Examination Debate Association (CEDA) evidence guidelines, is that underlined fragments must form coherent sentences and accurately represent the author's argument when read in isolation. Skipping connective words like "not" or "however" to flip an author's meaning is treated as a serious offense.

Underlining is also significant in card cutting workflows. Debaters using software such as Verbatim (a Microsoft Word template widely adopted since the late 2000s) underline directly in the document, with formatting macros that distinguish tag, cite, underline, and highlight layers. Judges reviewing evidence after a round typically read only the underlined portions but may examine surrounding text if a challenge arises.
