The word "relined" is spelled with the "re-" prefix, followed by the "line" root word, and then the "-d" suffix. In IPA phonetic transcription, it is spelled /riːˈlaɪnd/, with the stress on the second syllable.

The "-d" suffix indicates that the action of relining occurred in the past tense.
"Relined" is a verb that refers to the act of replacing or covering the inner surface of something with a new or different material. This process involves removing the existing lining and installing a fresh lining to restore or improve the functionality or appearance of an object or structure.
In the context of construction or home improvement, "relined" commonly describes the action of installing a new lining in chimneys. Chimney relining is necessary when the original lining becomes damaged, deteriorated, or outdated, posing a safety risk. The new lining typically consists of an appropriate material such as stainless steel, aluminum, or clay tiles, which is installed to increase efficiency, protect against heat, gas leaks, or creosote buildup, and ensure proper ventilation.
Additionally, the term "relined" can apply to the process of renewing the interior of pipes or pipelines. In this case, relining involves placing a lining material, such as epoxy resin or cured-in-place pipe (CIPP), inside the existing pipes, effectively creating a new inner surface. This method is often employed as a cost-effective alternative to pipe replacement, as it avoids the need for excavation and disruptive construction work.
Overall, the verb "relined" describes the action of replacing or renewing the interior surface or protective layer of an object, typically to enhance functionality, extend lifespan, or improve safety standards.
The word relined is formed by adding the prefix re- to the verb lined. The root word line comes from the Middle English word linen or linnen, which means to mark with lines. It ultimately derives from the Latin word linea, meaning a linen thread or string. Over time, line evolved to refer to any type of long, narrow mark or row, as well as the act of marking or drawing such lines. When re- is added as a prefix, it indicates repetition or restoration, resulting in relined, meaning to line again or to renew lining.
