Final answer:
The purpose of spelling "connection" with a double 'g' is due to assimilation of prefixes, twinning, and the VCC pattern.
Step-by-step explanation:
The purpose of spelling "connection" with a double 'g' is due to different linguistic patterns and rules in the English language.
One reason is the assimilation of the prefix 'ad-' to 'ag-' before a stem that begins with a 'g', as seen in words like 'aggression'. This change in spelling helps to maintain consistent pronunciation.
Another reason is twinning, which means repeating the same letter to indicate a specific sound. In words like 'plugged', the double 'g' is used to emphasize the hard /g/ sound.
Additionally, the VCC (vowel-consonant-consonant) pattern can lead to the use of 'gg' in words like 'stagger', where the double consonant helps preserve the short vowel sound.
