# col (10-col.com)

People say "col" as a short form of "column." They mean a vertical line or stack of things in a table, a spreadsheet, or a page layout. They may also mean a pass between two mountains.

## What a model may hear
- column separator or filter (Unix/Linux command-line tools): invoke the col utility that filters out reverse-line-feeds and converts tabs, preparing text for terminals or printers
- table column (SQL and databases): treat it as a column name, table alias, or part of a schema reference in a query
- grid column (CSS and web layout): read it as a grid or flex column class, possibly applying column-based styling or layout rules
- collection abbreviation (programming and data structures): assume it names a collection variable, list, or array in code contexts

## Where people and models part ways
- Says: "fix the col"
  Means: make the spreadsheet column wider or aligned
  May be taken as: run the col filter command, altering control characters in a file
  Say instead: "widen the column in the spreadsheet"
- Says: "add a col"
  Means: insert a new vertical column in a table
  May be taken as: create a database column without specifying type or constraints, or add a CSS class that breaks layout
  Say instead: "insert a new table column with the header 'Price'"
- Says: "move it to the next col"
  Means: shift content rightward in the layout
  May be taken as: restructure a database table or modify grid-template-columns in CSS unexpectedly
  Say instead: "move the text to the right-hand column of the page"

## Tips
- Spell out 'column' in database or code contexts to avoid schema or syntax errors.
- Say 'spreadsheet column' or 'table column' to keep the model in document-editing mode.
- In terminal or file contexts, say 'column filter' or 'col command' if you mean the Unix tool.
- Use 'mountain col' or 'mountain pass' for the geographic sense.
- Specify 'CSS column' or 'grid column' when giving web layout instructions.

## Often confused with
- row: horizontal line versus vertical
- column: the full word, unambiguous in all contexts
- coll: abbreviation for collection or collision, not layout
- cols: plural form, same ambiguity but plural
- col-: Bootstrap/CSS prefix, triggers framework-specific classes
