IPA: /rɪˈpleɪsəbl/
KK: /rɪˈpleɪsəbl/
Able to be exchanged for something else or substituted with another item.
The printer's ink cartridges are replaceable, so you can easily swap them out when they run out.
Replaceable → It is formed from "re-" (meaning again) and "place" (from Latin "locare", meaning to place). The suffix "-able" (meaning capable of) indicates that something can be placed again. Thus, replaceable means something that can be placed again or substituted.
Think of 'placing again' ('re-') something that can be 'put' ('place') in its position — that's why replaceable means it can be substituted.
