3.2 Grammatical Classification

‘Scan’ is a transitive verb, meaning it typically takes a direct object (e.g., scan the image).

It is generally a regular verb in modern English, forming its past tense by adding -ed. Historically, some dialects used ‘scan’ as both present and past (like ‘cut’ or ‘put’), but this is now archaic.

Main forms:

  • Base form: scan
  • Present participle (gerund): scanning
  • Past tense: scanned
  • Past participle: scanned

4. Structural Breakdown

4.1 Regular Past Tense Formation

‘Scan’ is a regular verb, so its past tense and past participle are formed by adding -ed to the base:

scan → scanned

Pronunciation: The -ed ending is pronounced as a voiced /d/, resulting in /skænd/.

Verb Form Example Pronunciation
Base form I scan documents daily. /skæn/
Past tense I scanned the document. /skænd/
Past participle I have scanned the images. /skænd/
Present participle I am scanning the files. /ˈskænɪŋ/

4.2 Irregular Past Tense Possibility

Historically, in some dialects or older English usage, ‘scan’ sometimes functioned as both present and past (similar to ‘cut’). However, this is now considered archaic or dialectal. Modern standard English uses ‘scanned’ exclusively as the past tense and past participle.

Etymology: ‘Scan’ comes from Latin scandere (“to climb” or “to scan verse”), adopted into English via Old French and Middle English. Initially linked to poetic analysis, it later broadened in meaning.
