Matches

Show answer & explanation

Answer

The correct pairings match 'ante-' with 'Before or prior in time and order', 'circum-' with 'Around or on all sides', 'contra-' with 'Against or in direct opposition', and 'intra-' with 'Within or located on the inside'.
Each prefix corresponds directly to its standard Latin morphological root: 'ante-' indicates priority in time or position ('before'), 'circum-' indicates perimeter or surrounding movement ('around'), 'contra-' indicates contrary action or resistance ('against'), and 'intra-' denotes internal containment ('within').

Step-by-Step Solution

1
Analyze the prefix 'ante-' and examine its root function.
'ante-' functions as a temporal and spatial prefix meaning 'before' or 'preceding' (e.g., antecedent, antedate).
Isolating the temporal meaning matches it with prior time and order.
2
Analyze the prefix 'circum-' and examine its root function.
'circum-' specifies a perimeter or spatial enclosure meaning 'around' or 'about' (e.g., circumference, circumscribe).
Recognizing spatial boundary relations verifies the match with surrounding or on all sides.
3
Analyze the prefix 'contra-' and examine its root function.
'contra-' indicates opposition or conflict meaning 'against' or 'contrary' (e.g., contradict, contravene).
Identifying oppositional morphology links the prefix directly to direct opposition.
4
Analyze the prefix 'intra-' and examine its root function.
'intra-' denotes interior confinement meaning 'within' or 'on the inside' (e.g., intravenous, intramural).
Distinguishing interior prefixes from interpersonal or transitional prefixes establishes the internal match.

Items

peri- (as in perimeter, periscope)
dys- (as in dysfunction, dystrophy)
bene- (as in benefactor, beneficial)
trans- (as in transport, transmit)

Matches

Show answer & explanation

Answer

The prefix peri- corresponds to 'Around, surrounding, or enclosing'; dys- corresponds to 'Abnormal, impaired, or bad'; bene- corresponds to 'Good, well, or favorable'; and trans- corresponds to 'Across, through, or beyond'.
Each prefix aligns with its standard morphological definition: 'peri-' means around or surrounding; 'dys-' means abnormal, impaired, or bad; 'bene-' means good, well, or favorable; and 'trans-' means across, through, or beyond.

Step-by-Step Solution

1
Analyze the Greek prefix 'peri-' using recognizable exemplar terms.
In words like 'perimeter' (distance around) and 'periscope' (instrument to view around obstacles), 'peri-' expresses the concept of surrounding or enclosing.
Isolating the morphological boundary identifies the positional/spatial meaning.
2
Analyze the Greek prefix 'dys-' using contextual examples.
In words like 'dysfunction' (impaired operation) and 'dystrophy' (faulty nutrition/development), 'dys-' functions as a negative qualitative marker meaning bad or abnormal.
Differentiating qualitative prefixes prevents confusion with purely locational prefixes.
3
Analyze the Latin prefix 'bene-' and its antonymous relationships.
In words like 'beneficial' and 'benevolent', 'bene-' consistently contributes the meaning of good or well.
Connecting prefixes to known Latin roots confirms positive evaluative meaning.
4
Analyze the Latin prefix 'trans-' across physical and directional uses.
In words like 'transport' (carry across) and 'transmit' (send through/across), 'trans-' denotes movement across or through.
Determining directional prefixes completes the distinct set of pairings.

Show answer & explanation

Answer: too subtle or slight to be noticed

Answer

too subtle or slight to be noticed
The word 'imperceptible' combines the negative prefix 'im-' (meaning 'not') with 'perceptible' (capable of being perceived). Therefore, something that is imperceptible is too slight, subtle, or gradual to be detected.

Step-by-Step Solution
