Words Ending in -ed and -ing

The endings -ed and -ing are inflectional endings: they change how an action word works in a sentence without creating an unrelated base meaning. This page uses clear examples in which the base spelling remains unchanged. The separate Spelling Rules for Adding Suffixes page teaches what happens in words such as running or making.

Find the base word first

Base word	Past action with -ed	Action in progress with -ing
jump	jumped	jumping
help	helped	helping
play	played	playing
rest	rested	resting

In these examples, spelling the base word first makes the ending easy to see: help + ed = helped and help + ing = helping. The ending -ed commonly marks a completed or past action. The ending -ing combines with a helping verb in a sentence, as in “They are helping,” to show an action in progress.

This is enough grammar to support the spelling decision. The page does not attempt to teach every verb tense or every use of an -ing form.

What to notice

• The same base word can take either ending: jumped/jumping.
• The letters e and d are present in every regular -ed spelling, even when both are not heard as a separate syllable.
• In rested, -ed adds a syllable. In jumped and played, it does not.
• The -ing ending is always written with i-n-g in these examples; do not write only the final sound.

Listen, but keep the spelling stable

Compare jumped, played, and rested. Their -ed endings are pronounced differently: jumped ends with a sound like /t/, played with a sound like /d/, and rested with an extra syllable. The pronunciation changes smoothly after different final sounds, but the regular ending is spelled -ed each time.

This pronunciation comparison has one spelling purpose: it prevents a learner from writing jumpt or omitting the e in rested. It is not necessary to memorize sound-category labels before learning the written ending.

Common mistakes and boundaries

Spelling only what the ending seems to sound like. If a learner writes jumpt, ask for the base word jump, then add the known past ending -ed.

Losing letters from the base. Build help + ing with separate cards or colors, then join the parts without deleting anything.

Applying the unchanged-base examples to every word. Words such as run → running, make → making, and carry → carried need a spelling change. Notice that they are different, but teach their conditions on Spelling Rules for Adding Suffixes rather than adding three new rules here.

A short teaching routine

1. Say a base action word, such as help, and use it in a present-time sentence.
2. Change the sentence to a past action and build help + ed.
3. Use a helping verb to show action in progress and build help + ing.
4. Underline the unchanged base in both completed words.
5. Mix several pairs and ask the learner to identify the base and ending before spelling.

If the learner struggles, separate the task. First ask for the base word alone. Then ask what the sentence needs—past action or action in progress—and supply two ending cards to choose from. Read back exactly what was written so the learner can decide whether the difficulty lies in the base, the choice of ending, or the ending’s fixed letters.

Signs the pattern is becoming secure

Signs of security include finding the base in a new regular example, choosing -ed or -ing from sentence meaning, preserving an unchanged base, and spelling -ed correctly despite its different pronunciations. A secure learner also notices when a base appears to change and knows to use a different spelling-rule strategy rather than guessing.
