Lockup
The fixed arrangement of logo parts (icon, name, tagline) with locked spacing and scale, treated as one unit you never rearrange.

What it is
A lockup is the fixed spatial relationship between the parts of a logo: symbol, wordmark, and sometimes a tagline or descriptor. The gap, the alignment, and the relative sizes are all specified once, and from then on the whole thing scales as a single locked object. Move one piece and it stops being the logo.
You reach for the word when handing files to other people. 'Use the horizontal lockup' means: take this exact arrangement, do not rebuild it. Guidelines usually express the spacing in a unit taken from the mark itself (half the icon width, one cap height) so it survives any size. Related flavors: a co-brand lockup pairs two logos with a divider rule, and a brand signature locks the logo to a tagline or an endorsement line.
The gotcha is people recreating lockups by hand in Canva or Figma, eyeballing the gap and resizing the icon 'just a bit' so it matches the cap height. That is exactly the failure mode. Ship a flattened master file per lockup and let nobody assemble it from loose parts. Optical spacing also beats mathematical spacing: a round icon usually needs slightly more room than a square one to look equally distant.

Build a horizontal logo lockup from this icon and wordmark: align the icon to the optical center of the wordmark's cap height, set the gap between them to half the icon's width, and match the icon height to the wordmark's cap height plus a small optical adjustment. Lock the group so both elements scale together. Export a flattened master with transparent background, plus a stacked lockup using the same spacing unit measured vertically. Show the spacing unit as an annotated diagram.
