| Lightly |
| In a light way |
| In an easy way |
| With lightness |
| In a breezy way |
| In an offhand way |
| In a light manner |
| In a jaunty manner |
| How lilts are sung |
| In a breezy manner |
| With a certain ease |
| In a carefree manner |
| How snobs often speak |
| Without really thinking |
| Without serious consideration |
| I have high hopes for aviation science," Tom said ___ |
