Pictogram (象形) – a kind of agricultural tool used for tilling the fields and removing weeds (Guo, 1931; Qiu, 1992), possibly made of a kind of large clam 蜃 (OC *djɯns, *djɯnʔ, *djins) (Guo, 1931).

Alternatively, it could be a pictogram (象形) of a person holding onto a cliff – original character of 振 (OC *tjɯn, *tjɯns, “to hold up”) (Shang, 1983).

“to vibrate”

Related to 震 (OC *tjɯn, “to shake”) and 振 (OC *tjɯn, *tjɯns, “to excite”), from Proto-Sino-Tibetan *dar ~ d(u/i)r (“to tremble; to shiver”) (Schuessler, 2007).

“fifth earthly branch”

Norman (1985) suggests that it is from Austroasiatic; compare Proto-Austroasiatic *tlan (“python”), whence Vietnamese trăn, Khmer ថ្លាន់ (thlan), Mon ကၠန် (klɔn). However, Ferlus (2013) points to reconstructions like *dər (Baxter & Sagart) and *ᴸdzɨr (Ferlus) and remarks that those do not match any animal's name in Mainland Southeast Asian (MSEA) languages. Therefore, 辰 might have been associated arbitrarily with the dragon (龍).

Smith (2011) agrees with the proposal (e.g. by Guo, 1931) that 辰 (OC dən) initially depicted an agricultural implement made from clams' shells and was the original form of 蜃 (OC dəns, “mollusc, clam”); so he proposes that the fifth earthly branch depicted the moon's second waning-gibbous phase, which looks like a clam. He also suggests that 辰 (chén) also represented the ovoid-shaped rising sun and is thus related to 晨 (chén, “early morning”).

“time”

From 時 (OC *djɯ, “time”) + nominalizing suffix -n, literally “that which is proceeding” (Schuessler, 2007). This word partially converges with 晨 (OC *djɯn, *ɦljɯn, “morning”) (ibid.).

“heavenly body”

The endopassive of 振 (OC *tjɯn, *tjɯns, “to shake; to stir”), literally “to stir oneself”, i.e. “when life begins to stir” > “heavenly bodies that mark time” (ibid.).
