Analyzing the Options for SHALLOW

Let's look at the given options and determine their meanings:

1. hollow
2. superficial
3. spiteful
4. deep

Analyzing Option 1: hollow

The word 'hollow' usually means having a space inside; not solid. It can also mean without value or substance, like a hollow victory. While related to emptiness, it's not typically the opposite of SHALLOW, especially in terms of physical depth.

Analyzing Option 2: superficial

'Superficial' means existing or occurring on the surface; appearing to be true or real only until examined more closely. It can also mean not thorough, deep, or complete, or concerned only with the obvious or apparent. This word is actually a SYNONYM for the second meaning of SHALLOW (lack of substance). So, it is not an antonym.

Analyzing Option 3: spiteful

'Spiteful' means showing or caused by malice; wishing to annoy, hurt, or offend someone. This word relates to emotions and intentions towards others. It has no direct relationship in meaning to SHALLOW, whether in terms of depth or substance. Therefore, it is not an antonym.

Analyzing Option 4: deep

The word 'deep' means having a large distance from the top or surface down to the bottom. It is the direct opposite of the primary meaning of SHALLOW (not deep). In the context of meaning or thought, 'deep' can also mean profound or insightful, which is the opposite of the 'lack of substance' meaning of SHALLOW. Thus, 'deep' serves as a clear antonym for SHALLOW in its most common uses.

Why 'deep' is the Antonym of SHALLOW

Comparing the meanings of SHALLOW and 'deep', it is clear that they are direct opposites. If something is SHALLOW, it lacks depth. If something is 'deep', it has significant depth. This holds true for both physical depth and the depth of ideas or feelings.
