thin strong rope-like string
A long, strong piece of string or rope that you use to tie or hold things.
用法パターン：
a length of cord to tie [something]
よくある間違い：
Learners sometimes confuse "cord" with "chord" (a group of musical notes). "Cord" is for rope-like things; "chord" is for music. Learners may also overuse "rope" and not realize that "cord" is more natural for thinner, neater, or decorative material.
類義語
string (Often thinner or weaker; used for lighter things like balloons or small packages.)

rope (Usually thicker and heavier than cord; used for very strong jobs like climbing or towing.)

flexible cable for electricity
A thick wire covered in plastic that connects an electrical device to the wall or to power.
用法パターン：
to plug the cord into [something]
よくある間違い：
Learners sometimes say "wire" when "cord" or "cable" is more natural, especially for things like phone chargers and laptop chargers. "Wire" sounds thinner or unfinished, without plastic around it.
類義語
cable (Very close in meaning, but "cable" is broader and can refer to data cables or very thick industrial cables, not only power cords.)

tie something with cord
To use a cord to tie or hold things together.
用法パターン：
to cord [something] (together/up)
よくある間違い：
This verb is not very common, so learners often say "tie" or "tie up" instead. That is usually fine and more natural in everyday speech. Use "cord" as a verb mainly in written or more careful descriptions.
類義語
