Difficulty: EasyWord Formation: Prefixes, Suffixes, and Roots

Complete the sentence below by supplying the appropriate word formed by adding the correct suffix to the root word 'harm'.

Answer:The chemist confirmed that the clear liquid was completely 【harmless】 and safe to handle without protective gloves.

Answer

harmless
The correct word is 'harmless'. Adding the derivative suffix '-less' to the noun root 'harm' creates an adjective meaning 'causing no harm' or 'safe', which perfectly matches the context of being safe to touch without gloves.

Step-by-Step Solution

1
Determine the required meaning of the word from the context of the sentence.
The sentence indicates that the liquid is 'safe to handle without protective gloves', meaning it causes no harm.
Contextual clues like 'safe to handle' require an adjective that denotes the absence of harm.
2
Apply the appropriate negative suffix to the root noun 'harm'.
Attaching the suffix '-less' to 'harm' forms the adjective 'harmless'.
The suffix '-less' means 'without' or 'free from', converting the noun 'harm' into an adjective meaning 'without harm'.
